Overview
The DAC8532IDGKRG4, produced by Texas Instruments, is a dual-channel, 16-bit digital-to-analog converter (DAC) that offers low power operation and a flexible serial host interface. This device is designed for applications requiring high precision and low power consumption. 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 compatible with SPI, QSP, and Microwire interface standards, and it can operate with input data clock frequencies up to 30 MHz at 5 V.
