Overview
The DAC8420FSZ is a quad 12-bit serial voltage-output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This monolithic device utilizes BiCMOS technology, offering high circuit density and low power consumption. It features a simple, 3-wire serial digital interface that can be easily interfaced with microprocessors running at 10 MHz with minimal additional circuitry. The DAC8420FSZ is available in a 16-lead SOIC wide package and is designed for a wide range of supply voltages, from +5 V to ±15 V, with corresponding reference voltages.
