AD7249ARZ Description

Short technical summary and product information.

The AD7249ARZ is a dual 12-bit, voltage-output digital-to-analog converter (DAC) from the DACPORT series by Analog Devices. It integrates two complete DACs with output amplifiers and a Zener voltage reference on a single monolithic CMOS chip, requiring no external trims for full specified performance.

 

Key electrical specifications include a 12-bit resolution, 10 µs settling time, and an update rate of 125 kHz. The device supports multiple output voltage ranges: 0 V to +5 V, 0 V to +10 V, and ±5 V. It uses an R-2R architecture and offers both external and internal reference options. The data interface is SPI, with data formats including natural binary for unipolar ranges and offset binary or twos complement for bipolar operation.

 

The AD7249ARZ is supplied in a 16-SOIC surface-mount package and operates over a temperature range of -40 °C to +85 °C. It requires an analog supply voltage of ±10.8 V to 16.5 V.
