DESCRIPTION
The ADC71 is a low cost, high quality, 16-bit succes-
sive approximation analog-to-digital converter. It uses
laser-trimmed ICs and is packaged in a convenient
32-pin hermetic ceramic dual-in-line package. The
converter is complete with internal reference, clock,
comparator, and thin-film scaling resistors, which
allow selection of analog input ranges of
±2.5V, ±5V,
±10V,
0 to +5V, 0 to +10V and 0 to +20V.
Data is available in parallel and serial form with
corresponding clock and status output. All digital in-
puts and outputs are TTL-compatible.
Power supply voltages are
±15VDC
and +5VDC.
