AD5683RBRMZ-RL7

Overview

The AD5683RBRMZ-RL7 is a single-channel, 16-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 guarantees monotonicity by design and offers selectable output spans of 0 V to VREF or 0 V to 2 × VREF. Key performance metrics include ±2 LSB maximum INL (B Grade), ±1 LSB DNL, and a settling time of 5 µs. It utilizes a versatile 3-wire SPI interface supporting clock rates up to 50 MHz and includes power-down modes for low current consumption.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL (B Grade) and ±1 LSB DNL
• Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient
• Selectable output span: 0 V to VREF or 0 V to 2 × VREF
• 3-wire SPI serial interface with data rates up to 50 MHz
• Power-down mode reduces current consumption to 2 µA maximum at 5 V

Applications

• Process control systems
• Data acquisition systems
• Digital gain and offset adjustment circuits
• Programmable voltage sources

Procurement Notes

Verify the specific grade (A or B) required for your application, as INL specifications differ between grades. Confirm that the MSOP-10 package variant matches your PCB footprint requirements. Ensure the internal reference capability aligns with system calibration needs, noting that some variants in this family may require external references.

Selection Notes

Select the AD5683RBRMZ-RL7 when high relative accuracy and low drift are critical without requiring external reference components. Consider the 10-lead MSOP package for space-constrained designs. Verify logic voltage compatibility, as the device supports independent logic supplies down to 1.62 V. Evaluate power consumption requirements against the normal mode current of approximately 500 µA.

Part Context

This component belongs to the AD5683R series within Analog Devices' nanoDAC+ portfolio. It is functionally similar to the AD5683 (external reference only) but includes an integrated reference. Other family members include the 14-bit AD5682R and 12-bit AD5681R, which share pinouts and interfaces but offer lower resolution.

Replacement Considerations

Public confirmed substitute part numbers: AD5683RARMZ, AD5683RACPZ-RL7.
