Overview
The AD5552BRZ, produced by Analog Devices Inc., is a single, 14-bit, serial-input, voltage-output Digital-to-Analog Converter (DAC). This DAC operates from a single supply voltage ranging from 2.7 V to 5.5 V and provides 14-bit performance without any adjustments. The unbuffered voltage output reduces power consumption and offset errors, and it can drive 60 kΩ loads directly. The AD5552BRZ is available in a 14-lead NSOIC package and features a versatile 3-wire interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards.
