Overview
The AD5063BRMZ from Analog Devices Inc. is a versatile and reliable 16-bit Digital-to-Analog Converter (DAC) designed for low power applications. It operates from a single supply voltage range of 2.7 V to 5.5 V and is part of the nanoDAC™ family. This device offers high accuracy with a relative accuracy specification of ±1 LSB and ensures monotonic operation with a ±1 LSB DNL specification. The AD5063BRMZ comes in a 10-lead MSOP package and includes on-board resistors, allowing for the generation of bipolar signals using an output amplifier. It features a 3-wire serial interface compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards, and it includes a power-on reset circuit and a software-selectable power-down mode to minimize power consumption.
