ADC-HX, ADC-HZ Series
12-ꢀit, 8 and 20μsec Analog-to-Digital Converters
PRODUCT OVERVIEW
The ADC-HX and ADC-HZ Series are self-
contained, high-performance, 12-bit A/D convert-
ers manufactured with thick and thin-film hybrid
technology. They use the successive approximation
conversion technique to achieve a 12-bit conver-
sion in 20 and 8 microseconds, respectively. Five
input voltage ranges are programmable by external
pin connection. An internal buffer amplifier is also
provided for applications in which 50 megohm
input impedance is required.
ꢀoth models have identical operation except for
conversion speed. They can be short-cycled to give
faster conversions in lower-resolution applica-
tions. Use of the internal buffer amplifier increases
conversion time by 3 microseconds, the settling
time of the amplifier. Output coding is comple-
mentary binary, complementary offset binary, or
complementary two’s complement. Serial data is
also brought out. The package is a 32-pin ceramic
TDIP. Models are available for use in commercial
FEATURES
12-bit resolution
These converters utilize a fast 12-bit monolithic (0 to +70°C), industrial (–40 to +100°C), or military
8 or 20 microsecond conversion times
DAC which includes a precision zener reference
source. The circuit also contains a fast mono-
lithic comparator, a monolithic 12-bit successive
approximation register, a clock and a monolithic
buffer amplifier. Nonlinearity is specified at
1/2LSꢀ maximum.
(–55 to +125°C) operating temperature ranges.
MIL-STD-883 and DESC Standard Military Drawing
models are also available.

TECHNICAL NOTES
1. It is recommended that the 15V power input pins both be bypassed to ground with a 0.01μF ceramic
capacitor in parallel with a 1μF electrolytic capacitor and the +5V power input pin be bypassed to ground
with a 10μF electrolytic capacitor as shown in the connection diagrams. In addition, GAIN ADJUST (pin 27)
should be bypassed to ground with a 0.01μF ceramic capacitor. These precautions will assure noise free
operation of the converter.
PERFORMANCE
2. DIGITAL COMMON (pin 15) and ANALOG COMMON (pin 26) are not connected together internally, and
therefore must be connected as directly as possible externally. It is recommended that a ground plane be
run underneath the case between the two commons. Analog ground and 15V power ground should be
run to pin 26 whereas digital ground and +5V ground should be run to pin 15.

3. External adjustment of zero or offset and gain are made by using trimming potentiometers connected as
shown in the connection diagrams. The potentiometer values can be between 10k and 100k Ohms and
should be 100ppm/°C cermet types. The trimming pots should be located as close as possible to the con-
verter to avoid noise pickup. In some cases, for example 8-bit short-cycled operation, external adjustment
may not be necessary.

4. Short-cycled operation results in shorter conversion times when the conversion is truncated to less than
12 bits. This is done by connecting SHORT CYCLE (pin 14) to the output bit following the last bit desired.
For example, for an 8-bit conversion, pin 14 is connected to the bit 9 output. Maximum conversion times
are given for short-cycled conversions of 8 or 10 bits. In these two cases, the clock rate is accelerated by
connecting the CLOCK RATE adjust (pin 17) to +5V (10 bits) or +15V (8 bits). The clock rate should not be
arbitrarily speeded up to exceed the maximum conversion rate at a given resolution, as missing codes will
result.

5. Note that output coding is complementary coding. For unipolar operation it is complementary binary, and
for bipolar operation it is complementary offset binary or complementary two’s complement. In cases in
which bipolar coding of offset binary or two’s complement is required, this can be achieved by inverting the
analog input to the converter (using an op amp connected for gain of –1). The converter is then calibrated
so that –FS analog input gives an output code of 0000 0000 0000, and +FS – 1LSꢀ gives 1111 1111 1111.

6. These converters can be operated with an external clock. To accomplish this, a negative pulse train is
applied to START CONVERT (pin 21). The rate of the external clock must be lower than the rate of the
internal clock as adjusted (see Short Cycle Operation tables) for the converter resolution selected. The
pulse width of the external clock should be between 100 and 300 nanoseconds. Each N-bit conversion
cycle requires a pulse train of N + 1 clock pulses for completion, e.g., an 8-bit conversion requires 9 clock
pulses for completion. A continuous pulse train may be used for consecutive conversions, resulting in an
N-bit conversion every N + 1 pulses, or the E.O.C. output may be used to gate a continuous pulse train for
single conversions.

7. When the input buffer amplifier is used, a delay equal to its settling time must be allowed between the input
level change, such as a multiplexer channel change, and the negative-going edge of the START CONVERT
pulse. If the buffer is not required, ꢀUFFER INPUT (pin 30) should be tied to ANALOG COMMON (pin 26). This
prevents the unused amplifier from introducing noise into the converter. For applications not using the buffer,
the converter must be driven from a source with an extremely low output impedance.

Use the input connection table for the desired input voltage range and
input impedance. Apply START CONVERT pulses of 100 nanoseconds
minimum duration to pin 21. The spacing of the pulses should be no
less than the maximum conversion time.
