Overview
The PM7543FSR, produced by Analog Devices Inc., is a 12-bit resolution, multiplying, CMOS Digital-to-Analog Converter (DAC). This component features serial data input and current output, which reduces the pin count and allows for a smaller package, saving PC board space. The PM7543FSR is designed to be a superior, pin-compatible second-source to the industry standard AD7543, offering improved analog parameters such as digital charge injection, power supply rejection, output capacitance, and feedthrough error. It also includes enhanced ESD protective circuitry and fast microprocessor interface capabilities.
