The AD1376/AD1377 are high resolution, 16-bit analog-todigital converters with internal reference, clock and laser-trimmed thin-film applications resistors. They are packaged in a compact 32-pin, ceramic scam sealed (hermetic) dual-in-line packages (DIP). Thin-film scaling resistors provide bipolar input ranges of 2.5 V, 5 V, 10 V and unipolar input ranges of 0 V to +5 V, 0 V to +10 V and 0 V to +20 V. Digital output data is provided in parallel and serial form with corresponding clock and status outputs. All digital inputs and outputs are TTL compatible.
