AD5696RARUZ

Overview

The AD5696RARUZ is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It integrates a 2.5 V internal reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device features a 400 kHz I2C-compatible serial interface, user-selectable gain of 1 or 2, and power-on reset options for zero or midscale initialization. Packaged in a 16-lead TSSOP, it delivers high relative accuracy with ±2 LSB maximum INL and low glitch impulse of 0.5 nV-sec.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum relative accuracy (INL).
• Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient.
• 400 kHz I2C serial interface with 1.8 V logic compatibility.
• User-selectable gain (×1 or ×2) via GAIN pin for flexible output spans.

Applications

• Optical transceivers
• Base-station power amplifiers
• Process control PLC I/O cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'RUZ' corresponds to the 16-lead TSSOP package configuration when sourcing. Confirm that the internal reference is enabled by default as per the standard device configuration. Ensure the ordering part number matches the required grade (A or B) for specified accuracy parameters.

Selection Notes

Select this component for applications requiring four independent 16-bit outputs with high precision. The integrated 2 ppm/°C reference eliminates external reference requirements. Verify that the 400 kHz I2C bus speed meets system timing constraints and that the TSSOP-16 footprint fits the PCB layout.

Part Context

This part belongs to the AD5696R/AD5695R/AD5694R family, differentiated primarily by resolution (16-bit, 14-bit, and 12-bit respectively). All variants share the same I2C interface, pinout, and internal reference architecture, allowing for design flexibility across different accuracy requirements within the same product line.

Replacement Considerations

The AD5696BCPZ-RL7 serves as a functional replacement offering identical specifications but utilizes a 3 mm × 3 mm LFCSP-16 package instead of the TSSOP-16. Pin compatibility remains consistent, though thermal management and PCB layout guidelines differ due to the exposed pad requirement of the LFCSP package.
