Overview
The AD7541AKNZ is a high-performance, 12-bit monolithic multiplying digital-to-analog converter (DAC) produced by Analog Devices Inc. It is fabricated using advanced, low noise, thin film, complementary metal-oxide semiconductor (CMOS) technology. This DAC is designed to offer improved specifications and performance over its predecessor, the AD7541, and is functionally and pin compatible with the industry standard AD7541. The AD7541AKNZ is available in an 18-lead PDIP package and is latch-up free, eliminating the need for output protection Schottky diodes.
