Overview
The AD5065BRUZ, produced by Analog Devices Inc., is a fully accurate 16-bit dual buffered voltage output nanoDAC®. This device is part of the AD5025/AD5045/AD5065 series, which offers high precision and low power consumption. It operates from a single 4.5 V to 5.5 V supply and features individual reference pins for each DAC, ensuring relative accuracy specifications of ±1 LSB INL and differential accuracy of ±1 LSB. The AD5065BRUZ is housed in a 14-lead TSSOP package and is suitable for a wide range of applications requiring precise digital-to-analog conversion.

Key Features
- Low power consumption with typical power-down current of 400 nA at 5 V.
- Power-on reset circuit ensuring DAC output powers up to zero scale or midscale.
- Software selectable output loads while in power-down mode.
- LDAC function for simultaneous update of DAC outputs with user-selectable channels.
- Asynchronous CLR function to clear all DACs to a software-selectable code (0 V, midscale, or full scale).
- Hardware power-down lockout capability to prevent unwanted power-down.
- Reference buffer provided on-chip with external reference pin.
- 3-wire, low power Schmitt trigger serial interface compatible with SPI, QSPI, MicroWire, and DSP standards.
- Very low glitch on power-up.
