AD5666BRUZ-2 Quad 16-Bit Voltage Output DAC Integrated Circuit Chip 14-Lead TSSOP

The AD5666BRUZ-2 is a quad, 16-bit, buffered voltage output digital-to-analog converter operating from a 2.7 V to 5.5 V supply. This -2 version uses the 2.5 V on-chip reference, specified at 5 ppm/degrees C, and all four outputs are monotonic by design.

The four outputs can be updated simultaneously, which keeps multi-channel control loops aligned in time. The device is packaged in a 14-lead TSSOP, giving a compact quad 16-bit solution with the reference already integrated.

A low power serial interface compatible with SPI, QSPI, MICROWIRE and DSP standards handles programming, and the part operates with low supply current for portable and industrial instruments. The AD5666BRUZ-2 suits precision multi-channel trim, bias and calibration.

The AD5666 family covers several resolution, reference and package options. Because AD5666 devices are pin and software compatible within each package group, a design can move between AD5666 variants without rewriting firmware.
