GENERAL DESCRIPTION

The ADS-919 is a high-performance, 14-bit, 2MHz sampling
A/D converter. This device accurately samples full-scale input
signals up to Nyquist frequencies with no missing codes. The
ADS-919 features outstanding dynamic performance including
a THD of –74dB.

Housed in a small 24-pin DDIP or SMT (gull-wing) package,
the functionally complete ADS-919 contains a fast-settling
sample-hold amplifier, a subranging (two-pass) A/D converter,
a precise voltage reference, timing/control logic, and error­correction circuitry. Digital input and output levels are TTL.

Requiring ±15V (or ±12V) and +5V supplies, the ADS-919
typically dissipates 1.8W (1.5W for ±12V). The unit is offered
with a unipolar input (0 to +10V). Models are available for use
in either commercial (0 to +70°C) or military (–55 to +125°C)
operating temperature ranges. Applications include radar,
sonar, spectrum analysis, and graphic/medical imaging.

Footnotes:

➀ All power supplies must be on before applying a start convert pulse. All supplies

and the clock (START CONVERT) must be present during warmup periods. The
device must be continuously converting during this time. There is a slight
degradation in performance when using ±12V supplies.

➁ See Ordering Information for availability of ±5V input range. Contact DATEL for

availability of other input voltage ranges.

➂ A 2MHz clock with a 200ns wide start convert pulse is used for all production

testing. See Timing Diagram for more details.

TECHNICAL NOTES

1. Obtaining fully specified performance from the ADS-919
requires careful attention to pc-card layout and power
supply decoupling. The device's analog and digital ground
systems are connected to each other internally. For optimal
performance, tie all ground pins (14, 19 and 23) directly to a
large analog ground plane beneath the package.

Bypass all power supplies and the REFERENCE OUTPUT
(pin 21) to ground with 4.7µF tantalum capacitors in parallel
with 0.1µF ceramic capacitors. Locate the bypass capaci­tors as close to the unit as possible. If the user-installed
offset and gain adjusting circuit shown in Figure 2 is used,
also locate it as close to the ADS-919 as possible.

2. The ADS-919 achieves its specified accuracies without the
need for external calibration. If required, the device's small

initial offset and gain errors can be reduced to zero using
the input circuit of Figure 2. When using this circuit, or any
similar offset and gain-calibration hardware, make adjust­ments following warmup. To avoid interaction, always
adjust offset before gain.

3. When operating the ADS-919 from ±12V supplies, do not
drive external circuitry with the REFERENCE OUTPUT. The
reference's accuracy and drift specifications may not be
met, and loading the circuit may cause accuracy errors
within the converter.

4. Applying a start convert pulse while a conversion is in
progress (EOC = logic "1") initiates a new and inaccurate
conversion cycle. Data for the interrupted and subsequent
conversions will be invalid.

Zero/Offset Adjust Procedure

1. Apply a train of pulses to the START CONVERT input
(pin 16) so the converter is continuously converting. If
using LED's on the outputs, a 200kHz conversion rate will
reduce flicker.

2. Apply +305µV to the ANALOG INPUT (pin 20).

3. Adjust the offset potentiometer until the output bits are
all 0's and the LSB flickers between 0 and 1.

Gain Adjust Procedure

1. Apply +9.999085V to the ANALOG INPUT (pin 20).

2. Adjust the gain potentiometer until the output bits are all 1's
and the LSB flickers between 1 and 0.

CALIBRATION PROCEDURE

(Refer to Figures 2 and 3)
Any offset and/or gain calibration procedures should not be

implemented until devices are fully warmed up. To avoid
interaction, offset must be adjusted before gain. The ranges of
adjustment for the circuit of Figure 2 are guaranteed to
compensate for the ADS-919's initial accuracy errors and may
not be able to compensate for additional system errors.

All fixed resistors in Figure 2 should be metal-film types, and
multiturn potentiometers should have TCR’s of 100ppm/°C or
less to minimize drift with temperature.

A/D converters are calibrated by positioning their digital
outputs exactly on the transition point between two adjacent
digital output codes. This can be accomplished by connecting
LED's to the digital outputs and adjusting until certain LED's
"flicker" equally between on and off. Other approaches
employ digital comparators or microcontrollers to detect when
the outputs change from one code to the next.

For the ADS-919, offset adjusting is normally accomplished at
the point where the output bits are 0's and the LSB just
changes from a 0 to a 1. This digital output transition ideally
occurs when the applied analog input is +½ LSB (+305µV).

Gain adjusting is accomplished when all bits are 1's and the
LSB just changes from a 1 to a 0. This transition ideally
occurs when the analog input is at +full scale minus 1½ LSB's
(+9.999085V).

THERMAL REQUIREMENTS

All DATEL sampling A/D converters are fully characterized and
specified over operating temperature (case) ranges of
0 to +70°C and –55 to +125°C. All room-temperature
(T

A = +25°C) production testing is performed without the use of

heat sinks or forced-air cooling. Thermal impedance figures
for each device are listed in their respective specification
tables.

These devices do not normally require heat sinks, however,
standard precautionary design and layout procedures should
be used to ensure devices do not overheat. The ground and
power planes beneath the package, as well as all pcb signal
runs to and from the device, should be as heavy as possible to
help conduct heat away from the package.

Electrically-insulating, thermally-conductive "pads" may be
installed underneath the package. Devices should be
soldered to boards rather than "socketed", and of course,
minimal air flow over the surface can greatly help reduce the
package temperature.

In more severe ambient conditions, the package/junction
temperature of a given device can be reduced dramatically
(typically 35%) by using one of DATEL's HS Series heat sinks.
See Ordering Information for the assigned part number. See
page 1-183 of the DATEL Data Acquisition Components
Catalog for more information on the HS Series. Request
DATEL Application Note AN-8, "Heat Sinks for DIP Data
Converters", or contact DATEL directly, for additional
information.

Notes: 1. f

s = 2MHz.

2. The ADS-919 is an edge-triggered device. All internal operations
are triggered by the rising edge of the start convert pulse, which
may be as narrow as 20nsec. All production testing is performed
at a 2MHz sampling rate with 200nsec wide start pulses. For
lower sampling rates, wider start pulses may be used, however, a
minimum pulse width low of 20nsec must be maintained.
