AD5673RBCPZ-1

Low-Power 16-Channel 12-Bit Voltage Output DAC with I²C Interface and Internal Reference

Product Description

Product Overview

The AD5673RBCPZ-1 is a precision 12-bit digital-to-analog converter (DAC) with 16 independent buffered voltage outputs. It integrates a high-stability 2.5 V internal reference with very low temperature coefficient (2 ppm/°C), and supports a selectable gain option to achieve full-scale outputs of 2.5 V (gain=1) or 5 V (gain=2). Operating from a single 2.7 V to 5.5 V supply with an I²C-compatible serial interface, the device offers guaranteed monotonic performance across its range and power-down mode to minimize system power consumption. Ideal for applications requiring multiple precision analog outputs with low power and compact integration.
