AD5683RBRMZ-3-RL7

Overview

The AD5683RBRMZ-3-RL7 is a single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features a maximum integral nonlinearity (INL) of ±2 LSB and includes an enabled internal 2.5 V reference with a typical temperature coefficient of 2 ppm/°C. The device operates on a single analog supply of 2.7 V to 5.5 V and supports independent logic supplies from 1.62 V to 5.5 V. It utilizes a versatile 3-wire SPI interface with clock rates up to 50 MHz. Key specifications include a settling time of 5 µs, low glitch impulse of 0.1 nV-sec, and high drive capability of 20 mA.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL for high relative accuracy
• Integrated 2.5 V reference with 2 ppm/°C typical drift
• Selectable output span: 0 V to VREF or 0 V to 2 × VREF
• Low power consumption: 1.2 mW at 3.3 V; 2 µA max in power-down mode

Applications

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

Procurement Notes

Verify the specific grade and pin configuration associated with the suffix '-3' against the manufacturer's ordering guide. Confirm that the required package variant (MSOP-10) matches the design requirements. Ensure compatibility with the intended serial interface timing and logic voltage levels before finalizing procurement.

Selection Notes

Select this component when a single-channel 16-bit DAC with integrated precision reference is required in a small MSOP-10 package. It is suitable for applications needing rail-to-rail output swing and independent logic supply flexibility down to 1.62 V. Consider the AD5683 if an external reference is preferred, or the AD5682R/AD5681R for lower resolution needs.

Part Context

This part belongs to the AD5683R series, which also includes 14-bit (AD5682R) and 12-bit (AD5681R) variants. These devices share similar architectures and interfaces but differ in resolution and accuracy specifications. The AD5683R represents the highest resolution option in this specific nanoDAC+ sub-family with an internal reference.

Replacement Considerations

Direct functional substitutes within the same family include AD5683RARMZ and AD5683RACPZ, though package differences exist. For pin-compatible alternatives with different interfaces, consider the I2C-based AD5693R series.
