GENERAL DESCRIPTION

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 amplifier, a subranging (two-pass) A/D converter, a
precise voltage reference, timing/control logic, and error­correction 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.

➄ This is the time required before the A/D output data is valid after the analog input

is back within the specified range.

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 slight
degradation in performance when using ±12V supplies.

➁ See ordering information for availability of ±5V input range. Contact DATEL for

availability of other input voltage ranges.

➂ 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).

TECHNICAL NOTES

1. Obtaining fully specified 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 4.7µF tantalum
capacitors in parallel with 0.1µF ceramic capacitors. Locate
the bypass capacitors as close to the unit as possible.

2. The ADS-119 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 3 and 4. For
operation without adjustment, tie pin 17 to analog ground.
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.

4. Data is valid only for the time period (55ns, typical) shown in
Figure 2 even if the device is sampling at less than 10MHz.

CALIBRATION PROCEDURE

(Refer to Figures 3 and 4, Table 1)
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 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 "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-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 (+366µV).

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 converter is continuously converting.

2. Apply +366µV to the ANALOG INPUT (pin 19).

3. Adjust the offset potentiometer until the output bits are
1000 0000 0000 and the LSB flickers 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 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 1.

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. Electrically­insulating, 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.
