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.

*Absolute maximum ratings are limiting values to be applied individually, and beyond which the service ability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability.
The AD1376/AD1377 are excellent for use in high resolution applications requiring moderate speed and high accuracy or stability over commercial (0°C to +70°C) temperature ranges (for extended temperature ranges, the pin compatible AD1378 is recommended.) Typical applications include medical and analytic instrumentation, precision measurement for industrial robotics, automatic test equipment (ATE), and multichannel data acquisition systems, servo control systems or anywhere wide dynamic range is required A proprietary monolithic DAC and laser-trimmed thin-film resistors guarantee a maximum nonlinearity of ±0 003% (1/2 LSB14.) The converters may be short cycled to achieve faster conversion times 15 ms to 14 bits for the AD1376, or 8 ms to 14 bits for the AD1377.
