® ADC76 16-Bit ANALOG-TO-DIGITAL CONVERTER FEATURES q 16-BIT RESOLUTION q LINEARITY ERROR: ±0.003% max (KG, BG) q NO MISSING CODES GUARANTEED FROM –25°C TO +85°C q 17µs CONVERSION TIME (16-Bit) q SERIAL AND PARALLEL OUTPUTS DESCRIPTION The ADC76 is a high quality, 16-bit successive approximation analog-to-digital converter. The ADC76 uses state-of-the-art laser-trimmed IC thin-film resistors and is packaged in a hermetic 32-pin dual-in-line package. The converter is complete with internal reference, 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. Parallel Digital Output 16-Bit D/A Converter Reference 16-Bit Successive Approx.
