Overview
The AD5063BRMZ-1, part of the nanoDAC™ family from Analog Devices Inc., is a low-power, single 16-bit, unbuffered voltage-output Digital-to-Analog Converter (DAC). This device operates from a single supply voltage ranging from 2.7 V to 5.5 V. It is known for its high accuracy, with a relative accuracy specification of ±1 LSB and guaranteed monotonic operation with a ±1 LSB DNL specification. The AD5063BRMZ-1 features on-board resistors in a 10-lead MSOP package, enabling the generation of bipolar signals with an external output amplifier. The device uses a versatile 3-wire serial interface compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards, operating at clock rates up to 30 MHz.
