AD5405YCPZ Dual 12-Bit Multiplying DAC Integrated Circuit Chip 40-Lead LFCSP

The AD5405YCPZ is a dual, 12-bit, current output, multiplying digital-to-analog converter with four-quadrant resistors, designed for high bandwidth signal processing. Each channel accepts a plus or minus 10 V reference and multiplies it by the digital code.

The device operates from a 2.5 V to 5.5 V supply, draws 0.5 uA typical, and offers integral nonlinearity of plus or minus 1 LSB. The parallel interface allows fast code updates, and the 40-lead LFCSP with exposed pad keeps the dual-channel layout compact.

Specified from -40 degrees C to +125 degrees C, the AD5405YCPZ suits programmable gain and attenuation, waveform generation and modulation in industrial and communication equipment where two multiplying channels are needed.

The AD5405 family covers several resolution, reference and package options. Because AD5405 devices are pin and software compatible within each package group, a design can move between AD5405 variants without rewriting firmware.
