Overview
The PM7528GP, produced by Analog Devices Inc., is a dual 8-bit buffered multiplying CMOS digital-to-analog converter (DAC). This device features two independent 8-bit DACs, each with a thin-film R-2R resistor-ladder network and tracking span resistors. The monolithic construction of the PM7528GP ensures excellent DAC-to-DAC matching and tracking. It operates from a single power supply of 5 to 15 volts and dissipates only 20mW of power, making it a power-efficient solution. The device is packaged in a space-saving 20-pin 0.3" wide DIP package.
