GENERAL DESCRIPTION
INPUT/OUTPUT CONNECTIONS
The ADS-929 is a high-performance, 14-bit, 2MHz sampling
A/D converter. This device samples input signals up to Nyquist
frequencies with no missing codes. The ADS-929 features
outstanding dynamic performance including a THD of –79dB.
Housed in a small 24-pin DDIP or SMT (gull-wing) package,
the functionally complete ADS-929 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-929
typically dissipates 1.7W (1.4W for ±12V). The unit is offered
with a bipolar input (–5V to +5V). 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 0 to +10V input range. Contact DATEL for availability
of other input voltage ranges.
➄ This is the time required before the A/D output data is valid after the analog input
is back within the specified range.
➂ A 2MHz clock with a 200ns wide start convert pulse is used for all production
testing. See Timing Diagram for more details.
2. The ADS-929 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.
TECHNICAL NOTES
1. Obtaining fully specified performance from the ADS-929
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.
3. When operating the ADS-929 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.
Bypass all power supplies, as well as 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-929 as
possible.
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.

ADS-929
CALIBRATION PROCEDURE
Zero/Offset Adjust Procedure
(Refer to Figures 2 and 3)
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.
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-929's initial accuracy errors and may
not be able to compensate for additional system errors.
2. Apply +305µV to the ANALOG INPUT (pin 20).
3. Adjust the offset potentiometer until the output bits are
a 1 and all 0's and the LSB flickers between 0 and 1.
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.
Gain Adjust Procedure
1. Apply +4.999085V to the ANALOG INPUT (pin 20).
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.
2. Adjust the gain potentiometer until the output bits are all 1's
and the LSB flickers between 1 and 0.
Table 1. Zero and Gain Adjust
INPUT VOLTAGE
RANGE
For the ADS-929, offset adjusting 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 (+305µV).

THERMAL REQUIREMENTS
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.
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
(TA = +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.
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.
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.

2. The ADS-929 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.
