AD5429YRUZ Dual 8-Bit Multiplying DAC Integrated Circuit Chip 16-Lead TSSOP

The AD5429YRUZ is a dual, 8-bit, current output, multiplying digital-to-analog converter for signal processing applications requiring two independent multiplying channels. A plus or minus 10 V reference range allows four-quadrant multiplication of the input waveform.

The device runs from a 2.5 V to 5.5 V supply with 0.5 uA typical current consumption, and its 50 MHz serial interface supports fast code updates. Integral nonlinearity is plus or minus 0.25 LSB at 8 bits, keeping gain steps accurate.

Specified from -40 degrees C to +125 degrees C and supplied in a 16-lead TSSOP, the device suits programmable gain, attenuation and modulation in industrial and communication systems where board space and power are limited.

The AD5429 family covers several resolution, reference and package options. Because AD5429 devices are pin and software compatible within each package group, a design can move between AD5429 variants without rewriting firmware.
