GENERAL DESCRIPTION
The ADS-926 is a high-performance, 14-bit, 500kHz sampling
A/D converter. This device accurately samples full-scale input
signals up to Nyquist frequencies with no missing codes and
exhibits outstanding dynamic performance that surpasses
most 16-bit, 500kHz sampling A/D's. THD and SNR, for
example, are typically –90dB and 80dB when converting fullscale input signals up to 100kHz.
INPUT/OUTPUT CONNECTIONS
Housed in a small 24-pin DDIP or SMT (gull-wing) package,
the functionally complete ADS-926 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-926
dissipates only 1.75W (1.6W for ±12V), maximum. 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.

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-926
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 unit.
3. When operating the ADS-926 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 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-926 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.
2. The ADS-926 achieves its specified accuracies without the

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-926'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-926, 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-926 is a pulse-triggered device. Its internal operations
are triggered by both the rising and falling edges of the start
convert pulse. When sampling at 500kHz, the start pulse must be
between 175 and 225nsec wide. For lower sampling rates, wider
start pulses may be used, however, a 50nsec minimum pulse
width low must be maintained.
