AD5697RBRUZ-RL7

Overview

The AD5697RBRUZ-RL7 is a dual, 12-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device utilizes a 400 kHz I2C-compatible serial interface and supports user-selectable gain of 1 or 2 via the GAIN pin. Key performance metrics include a maximum total unadjusted error of ±0.1% FSR, a settling time of 7 µs, and low power consumption of 3.3 mW at 3 V. It is housed in a 16-lead TSSOP package.

Feature Summary

• Dual-channel 12-bit resolution with ±1 LSB DNL and INL
• Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient
• User-selectable gain (×1 or ×2) for full-scale outputs of 2.5 V or 5 V
• Power-on reset circuit with RSTSEL pin for zero or midscale initialization

Applications

• Base station power amplifiers
• Process controls including programmable logic controller I/O cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix BRUZ corresponds to the 16-lead TSSOP package variant when sourcing. Confirm that the RL7 designation indicates reel packaging. Ensure compatibility with the EVAL-AD5697RSDZ evaluation board if hardware validation is required during the procurement phase.

Selection Notes

Select this component for applications requiring dual-channel precision with minimal external reference components. The internal 2 ppm/°C reference reduces bill-of-materials complexity. Verify that the 1.8 V logic compatibility of the VLOGIC pin aligns with the host microprocessor interface levels.

Part Context

This part belongs to the AD5697R series within the nanoDAC+ family. It shares functional similarities with the AD5697RBCPZ-RL7 but differs in package type, utilizing TSSOP instead of LFCSP. Both variants offer identical electrical specifications and dual-channel architecture.

Replacement Considerations

The AD5697RBCPZ-RL7 serves as a package alternative offering identical electrical performance in an LFCSP form factor.
