ADS-943

14-Bit, 3MHz, Low-Distortion

Sampling A/D Converters

edge-triggered, requiring only the rising edge of a start convert
pulse to initiate a conversion.

The device is offered with a bipolar input range of ±2V. Models
are available for use in either commercial (0 to +70°C) or
military (–55 to +125°C) operating temperature ranges. A
proprietary, auto-calibrating, error-correcting circuit allows the
device to achieve specified performance over the full military
temperature range.

GENERAL DESCRIPTION

The low-cost ADS-943 is a 14-bit, 3MHz sampling A/D
converter optimized to meet the demanding dynamic-range
and sampling-rate requirements of contemporary digital
telecommunications applications. The ADS-943's outstanding
dynamic performance is evidenced by a peak harmonic
specification of –83dB and a signal-to-noise ratio (SNR) of
79dB. Additionally, the ADS-943 easily achieves the 2.2MHz
minimum sampling rate required by digital receivers in certain
ADSL, HDSL and ATM applications. The ADS-943 also
addresses size and power constraints normally associated with
these types of applications. This device requires just ±5V
supplies, dissipates 1.7 Watts, and is packaged in a very small
24-pin DDIP.

Although optimized for frequency-domain applications, the
ADS-943's DNL and noise specifications are also outstanding,
thereby making it an equally impressive device for time-domain
applications (graphic and medical imaging, process control,
etc.). In fact, the ADS-943 guarantees no missing codes to the
14-bit level over the full military operating temperature range.

The functionally complete ADS-943 contains a fast-settling
sample-hold amplifier, a subranging (two-pass) A/D converter,
an internal reference, timing/control logic, and error-correction
circuitry. Digital input and output levels are TTL. The unit is

TECHNICAL NOTES

1. Obtaining fully specified performance from the ADS-943
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 24) directly to a
large analog ground plane beneath the package.

Bypass all power supplies 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.

2. The ADS-943 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 adjustment circuitry shown in Figures 2 and 3.

When using this circuitry, or any similar offset and gain­calibration hardware, make adjustments following warmup.
To avoid interaction, always adjust offset before gain.

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

4. A passive bandpass filter is used at the input of the A/D for
all production testing.

Footnotes:

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

supplies and the clock (start convert pulses) must be present during warmup
periods. The device must be continuously converting during this time.

➁ Contact DATEL for other input voltage ranges.

➂ A 3MHz clock with a 20nsec positive pulse width is used for all production testing.

When sampling at 3MHz, the start convert pulse must be between 10 and
110nsec wide or between 160 and 300nsec wide. The falling edge must not occur
between 110 and 160nsec. For lower sampling rates, wider start pulses may be
used.

CALIBRATION PROCEDURE

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 circuits in Figures 2 and 3 are guaranteed to
compensate for the ADS-943's initial accuracy errors and may
not be able to compensate for additional system errors.

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.

Offset adjusting for the ADS-943 is normally accomplished at
the point where the MSB is a 1 and all other 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 (+122µV).

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
(+1.99963V).

Zero/Offset Adjust Procedure

1. Apply a train of pulses to the START CONVERT input
(pin 18) so the converter is continuously converting.

2. Apply +122µV to the ANALOG INPUT (pin 21).

3. Adjust the offset potentiometer until the output bits are
10 0000 0000 0000 and the LSB flickers between 0 and 1.

Gain Adjust Procedure

1. Apply +1.99963V to the ANALOG INPUT (pin 21).

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

3. To confirm proper operation of the device, vary the input
signal to obtain the output coding listed in Table 2.

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.

The start convert positive pulse width must be between either 10 and 110nsec or

160 and 300nsec (when sampling at 3MHz) to ensure proper operation. For sampling
rates lower than 3MHz, the start pulse can be wider than 300nsec, however a minimum
pulse width low of 30nsec should be maintained. A 3MHz clock with a 20nsec positive

pulse width is used for all production testing.
