DESCRIPTION
The ADC76 is a high quality, 16-bit successive ap-
proximation analog-to-digital converter. The ADC76
uses state-of-the-art laser-trimmed IC thin-film resis-
tors and is packaged in a hermetic 32-pin dual-in-line
package. The converter is complete with internal ref-
erence, short cycling capabilities, serial output, 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.
It is specified for operation over two temperature
ranges: 0°C to +70°C (J, K) and –25°C to +85°C (A, B).
Data is available in parallel and serial form with
corresponding clock and status output. All digital
inputs and outputs are TTL-compatible.
Power supply voltages are ±15VDC and +5VDC.
