AD5665RBRUZ-1

Overview

The AD5665RBRUZ-1 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It features an on-chip 2.5 V reference with a temperature coefficient of 5 ppm/°C, enabling a full-scale output range of 5 V. The device operates on a single 2.7 V to 5.5 V supply and supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) I²C interfaces. Key specifications include ±8 LSB relative accuracy, ±1 LSB differential nonlinearity, and rail-to-rail output swing. It incorporates power-on reset, per-channel power-down, and hardware LDAC/CLR functions.

Feature Summary

• Quad 16-bit resolution with on-chip 2.5 V, 5 ppm/°C reference
• I²C interface supporting standard, fast, and high-speed modes
• Rail-to-rail buffered voltage outputs with ±8 LSB relative accuracy
• Power-on reset to zero scale or midscale via POR pin configuration

Applications

• Process control systems
• Data acquisition systems
• Portable battery-powered instruments
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix '1' against the manufacturer's official ordering guide, as datasheets typically list '2' for TSSOP packages. Confirm package type and grade availability directly with Analog Devices or authorized distributors to ensure correct part identification.

Selection Notes

Select this component for applications requiring four independent 16-bit channels with low drift. Ensure the system supports I²C communication speeds up to 3.4 MHz if utilizing high-speed mode. Verify that the 2.7 V to 5.5 V supply range aligns with the target power architecture.

Part Context

This device belongs to the AD5625R/AD5645R/AD5665R series of nanoDACs. It shares functional similarities with the AD5665R but may differ in address bits or specific package variants defined by the suffix. It is part of a broader family including SPI-compatible versions like the AD5664R.

Replacement Considerations

The AD5665RBRUZ-2 is a documented variant within the same family, sharing identical electrical characteristics and pinout. Verify if the suffix change affects only packaging or addressing before substitution.
