GENERAL DESCRIPTION
The low-cost ADS-949 is a 14-bit, 12.8MHz sampling A/D converter. This
device accurately samples full-scale input signals up to Nyquist frequencies
with no missing codes. Excellent differential nonlinearity error (DNL), signalto-noise ratio (SNR), and total harmonic distortion (THD) make the ADS-949
the ideal choice for both time-domain (CCD/FPA imaging, scanners, process
control) and frequency-domain (radar, telecommunications, spectrum analysis) applications.
The functionally complete ADS-949 contains a fast-settling sample/hold
amplifier, a subranging A/D converter, an internal reference, timing/control
logic, and error-correction circuitry. Digital input and output levels are TTL.
The ADS-949 only requires the rising edge of a start convert pulse to operate.
Requiring only +15V, +5V and –5V supplies, the ADS-949 typically dissipates just 2 Watts. The device is offered with a Bipolar input range of ±2.5V
and Unipolar range of 0 to 5 volts. Models are available for use in either

➁ Contact DATEL for other input voltage ranges.
➂ A 50ns wide start convert pulse is used for all production testing. For
applications requiring less than an 12.8MHz sampling rate, wider start convert
pulses can be used. The rising edge of the start convert pulse needs to be as
sharp as possible (<10 ns). Otherwise, a degradation in performance can result
from a slow rising edge pulse.
TECHNICAL NOTES
1. Obtaining fully specified performance from the ADS-949 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 (26 and
29) 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-949 achieves its specified accuracies without the need
for external calibration. It is recommended that the +5VA and +5VD
supplies should be powered up from the same source. If required,
the device’s small initial offset and gain errors can be reduced to
DATEL, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 USA
zero using the adjustment circuitry shown in Figure 2, 3.
When using this circuitry, or any similar offset and gain calibration
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.

ADS 949
14 Bit, 12.8MHz Sampling A/D Converters
CALIBRATION PROCEDURE
Zero/Offset Adjust 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-949’s initial accuracy errors and may not
be able to compensate for additional system errors.
1. Apply a train of pulses to the START CONVERT input
(pin 7) so the converter is continuously converting.
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.
Gain Adjust Procedure
2. Apply +153μV to the ANALOG INPUT (pin 1).
3. Adjust the offset potentiometer until the output bits are
10 0000 0000 0000 and the LSB flickers between 0 and 1.
1. Apply +2.49954V to the ANALOG INPUT (pin 1).
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.
Offset adjusting for the ADS-949 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 (+153μV).
Table 1. Gain and Zero Adjust
INPUT VOLTAGE
RANGE
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 (+2.49954V).

Note: The Voltage Value at Pin 32 (Range) sets the input voltage range of the ADS-949
eg: If Pin 6 (2.5V Reference Out) is tied to the Range Pin 32 (20k Pot is shorted), then
the input range of the ADS-949 becomes ±2.5V
If the 20k Pot is set at midrange then the input range of the ADS-949 becomes ±1.25V

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 (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.
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 AN8, "Heat Sinks for DIP Data Converters", or contact
DATEL directly, for additional information.
