BLOCK DIAGRAM
The ADS-119 is a high-performance, 12-bit,
10MHz sampling A/D converter. The device
samples input signals up to Nyquist frequencies
with no missing codes. The ADS-119 features
excellent dynamic performance including a typical
SNR of 69dB.
Packaged in a metal-sealed, ceramic, 24-pin
DDIP, the functionally complete ADS-119 contains
a fast-settling sample/ hold amplifi er, a subranging
(two-pass) A/D converter, a precise voltage refer-
ence, timing/control logic, and error-correction
circuitry. All timing and control logic operates from
the rising edge of a single start convert pulse.
Digital input and output levels are TTL.
Requiring only ±5V supplies, the ADS-119
typically dissipates 1.8 Watts. The unit offers a
bipolar input range of ±1.5V. Models are available
for use in either commercial (0 to +70°C) or military
(–55 to +125°C) operating temperature ranges.
Typical applications include signal analysis,
medical/graphic imaging, process control, ATE,
radar, and sonar.

errors can be reduced to zero using the adjustment circuitry shown in

ground. When using this circuitry, or any similar offset and gaincalibra-

always adjust offset before gain.

Footnotes:
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 slight
degradation in performance when using ±12V supplies.
See ordering information for availability of ±5V input range. Contact DATEL for
availability of other input voltage ranges.
A 200ns wide start convert pulse is used for all production testing. Only the rising
edge of the start convert pulse is required for the device to operate
(edge-triggered).
1. Obtaining fully specifi ed performance from the ADS-119 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, 18, and 23) directly
to a large analog ground plane beneath the package. Bypass all power
supplies to ground with 4.7F tantalum capacitors in parallel with 0.1F
ceramic capacitors. Locate the bypass capacitors as close to the unit as
possible.
2. The ADS-119 achieves its specifi ed accuracies without the need for
external calibration. If required, the device's small initial offset and gain

CALIBRATION PROCEDURE
(Refer to Figures 3 and 4, Table 1)
Any offset and/or gain calibration procedures should not be implemented
ntil devices are fully warmed up. To avoid interaction, offset must be
adjusted before gain. The ranges of adjustment for the circuits in Figure
3 and 4 are guaranteed to compensate for the ADS-119'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 "fl icker" 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-119 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 (+366V).
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 1 ½ LSB's (+1.4989V).
Zero/Offset Adjust Procedure
1. Apply a train of pulses to the START CONVERT input (pin 16) so the con-
verter is continuously converting.
2. Apply +366V to the ANALOG INPUT (pin 19).
3. Adjust the offset potentiometer until the output bits are 1000 0000 0000
and the LSB fl ickers between 0 and 1.
Gain Adjust Procedure
1. Apply +1.4989V to the ANALOG INPUT (pin 19).
2. Adjust the gain potentiometer until all output bits are 1's and the LSB
ickers between 1 and 0.
3. To confi rm proper operation of the device, vary the input signal to obtain
the output coding listed in Table 1.

THERMAL REQUIREMENTS
All DATEL sampling A/D converters are fully characterized and speci-
ed 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 fi gures for each device are listed in their respective specifi ca-
tion 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 pack-
age, 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. Electrical-
lyinsulating, thermally-conductive "pads" may be installed underneath the
package. Devices should be soldered to boards rather than "socketed",
and of course, minimal air fl ow 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 Applica-
tion Note AN-8, "Heat Sinks for DIP Data Converters", or contact DATEL
directly, for additional information.
