(CC-DAC)

TDA1311A

FEATURES

• Voltage output

• Space saving packages SO8 or DIP8

• Low power consumption

• Wide dynamic range (16-bit resolution)

• Continuous Calibration (CC) concept

• Easy application:

– single 4 to 5.5 V rail supply
– output current and bias current are proportional to the

supply voltage

– integrated current-to-voltage converter

• Fast settling time permits 2, 4 and 8 × oversampling
(serial input) or double-speed operation at
4 × oversampling

• Internal bias current ensures maximum dynamic range

• Wide operating temperature range (−40 °C to +85 °C)

• Compatible with most current Japanese input formats:

time multiplexed, two's complement, TTL

• No zero-crossing distortion

• Cost efficient.

GENERAL DESCRIPTION

The TDA1311A; AT is a voltage-driven digital-to-analog
converter and is new generation of DAC devices which
embodies the innovative technique of Continuous
Calibration (CC). The largest bit-currents are repeatedly
generated by one single current reference source. This
duplication is based upon an internal charge storage
principle which has an accuracy insensitive to ageing,
temperature matching and process variations.

The TDA1311A; AT is fabricated in a 1.0 µm CMOS
process and features an extremely low-power dissipation,
small package size and easy application. Furthermore, the
accuracy of the intrinsic high coarse-current combined
with the implemented symmetrical offset decoding method
preclude zero-crossing distortion and ensures high quality
audio reproduction. Therefore, the CC-DAC is eminently
suitable for use in (portable) digital audio equipment.

TDA1311A

FUNCTIONAL DESCRIPTION

The basic operation of the continuous calibration DAC is
illustrated in Fig.3. The figure shows the calibration and
operation cycle. During calibration of the MOS current
source (see Fig.3a) transistor M1 is connected as a diode
by applying a reference current. The voltage Vgs on the
intrinsic gate-source capacitance Cgs of M1 is then
determined by the transistor characteristics. After
calibration of the drain current to the reference value I

REF

,
the switch S1 is opened and S2 is switched to the other
position (see Fig.3b). The gate-to-source voltage V

gs

of
M1 is not changed because the charge on Cgs is
preserved. Therefore, the drain current of M1 will still be
equal to I

REF

and this exact duplicate of I

REF

is now

available at the OUT terminal.
The 32 current sources and the spare current source of the

TDA1311A; AT are continuously calibrated (see Fig.1).
The spare current source is included to allow continuous
converter operation. The output of one calibrated source is
connected to an 11-bit binary current divider consisting of
2048 transistors.

A symmetrical offset decoding principle is incorporated
that arranges the bit switching in such a way that the
zero-crossing is performed only by switching the LSB
currents.

The TDA1311A; AT (CC-DAC) accepts serial input data
formats of 16-bit word length. Left and right data words are
time multiplexed. The most significant bit (bit 1) must
always be first. The input data format is shown in Figs 4
and 5.

With a HIGH level on the word select input (WS), data is
placed in the left input register and with a LOW level on the
WS input, data is placed in the right input register (see
Fig.1). The data in the input registers are simultaneously
latched in the output registers which control the bit
switches.

An internal offset voltage V

OS

is added to the full scale
output voltage VFS; VOS and VFS are proportional to VDD:
V

DD1/VDD2=VFS1/VFS2=VOS1/VOS2

.

Attention to printed circuit board layout

The TDA1311A and even more so the TDA1311AT offers
great ease in designing-in to printed-circuit boards due to
its small size and low pin count. The TDA1311A; AT being
a mixed-signal IC in CMOS, some attention needs to be
paid to layout and topology of the application PCB.
Following some basic rules will yield the desired
performance. The most important considerations are:

1. Supply: care should be taken to supply the
TDA1311A; AT with a clean, noiseless VDD, for a good
noise performance of the analog parts of the DAC.
Supply purity can easily be achieved by using an
RC-filtered supply.

2. Grounding: preferably a ground plane should be used,
in order to have a low-impedance return available at
any point in the layout. It is advantageous to make a
partitioning of the ground plane according to the nature
of the expected return currents (digital input returns
separate from supply returns and separate from the
analog section).

3. Topology: the capacitor decoupling high-frequency
supply interference from V

DD

to GND should be placed
as close as is physically possible to the IC body,
ensuring a low-inductance path to ground. The digital
input conductors may be shielded by ground leads
running alongside. The placement of a passive ground
plane underside the entire IC surface gives `free`
additional decoupling from the IC body to ground as
well as providing a shield between the digital input pins
and the analog output pins.

Figure 7 shows recommended layouts for printed-circuit
boards for the SO8 and DIL8 versions respectively. Both
layouts use a single-interconnect layer.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

(order code 9398 652 90011).

DIP

SOLDERING BY DIPPING OR BY WA VE
The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

R

EPAIRING SOLDERED JOINTS

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.

SO

REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO

packages.
Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

W

AVE SOLDERING

Wave soldering techniques can be used for all SO
packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream end.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

R

EPAIRING SOLDERED JOINTS

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
