Overview

Description

The DAC8420ESZ is a 12-bit, quad-channel, voltage-output digital-to-analog converter (DAC) from Analog Devices. It features serial SPI interface compatibility, low power consumption, and ±10V output range (with external reference).
Key features:
- Four independent DACs in a single package.
- 12-bit resolution with monotonic performance.
- SPI interface for easy microcontroller interfacing.
- Low glitch energy for stable output transitions.
- Wide supply range (±11.4V to ±16.5V for bipolar operation).
Applications include industrial control, automation, test equipment, and programmable voltage sources. The DAC8420ESZ comes in a 16-lead SOIC package (ESZ suffix) and offers reliable performance for precision analog output needs.
For detailed specs, refer to the datasheet.
