DESCRIPTION
The ADC803 is a high speed hybrid successive
approximation analog-to-digital converter utilizing
laser-trimmed thin film components.
It is complete with internal reference, clock, and
comparator, and is packaged in a 32-pin metal pack-
age. Conversion time is set at the factory to 1.5
μ
s.
With user-adjusted conversion time set at 1
μ
s,
±
1LSB
accuracy can be achieved. The gain and offset errors
may be externally trimmed to zero.
Internal scaling resistors are provided for the selection
of analog signal input ranges of 0V to –10V,
±
5V,
and
±
10V.
Output codes available are complementary binary
for unipolar inputs and bipolar offset binary for
bipolar inputs.
All digital inputs and outputs are TTL-compatible.
Power supply requirements are
±
15V and +5V.
