Overview
The DAC8532IDGKR is a dual-channel, 16-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power operation and features a flexible serial host interface. Each on-chip precision output amplifier allows for rail-to-rail output swing over a supply range of 2.7 V to 5.5 V. The DAC8532 supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 30 MHz for VDD = 5 V. It is particularly suited for portable battery-operated equipment and other low-power applications due to its micro-power operation and power-down feature.
