DAC8412EP

DAC8412EP Description

The DAC8412EP from Analog Devices Inc. is a 12-bit, quad-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 28-pin DIP package, this through-hole-mount device operates with a 5V digital supply and supports parallel data interface for straightforward integration into legacy systems. With a typical settling time of 10µs, it delivers rapid response for dynamic control applications. The DAC8412EP requires an external reference voltage, enabling flexibility in output range configuration. Although now classified as obsolete, its robust design and performance characteristics make it a reliable choice for existing systems requiring high-resolution analog outputs.
