The AD392 is a quad I2-bit, high-speed, voltage output digital-toanalog converter with readback in a 32-pin hermetically sealed package. The design is based on a custom IC interface to complete I2-bit DAC chips which reduces chip count and provides high reliability. The AD392 is ideal for systems requiring digital control of many analog voltages and for the monitoring of these analog voltages especially where board space is a premium. Such applications include ATE, robotics, process controllers and precision fIlters.
