Overview
The AD767JNZ is a microprocessor-compatible 12-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component integrates a high-stability buried Zener reference and an input latch on a single chip, making it a complete voltage output DAC. The AD767JNZ is designed for high accuracy and reliability, utilizing 12 precision high-speed bipolar current steering switches and a laser-trimmed thin-film resistor network. The on-chip latch allows for direct interface to 12-bit buses, supporting the fastest available microprocessors with strobe pulses as short as 40 ns.
