AD5683RBRMZ-3

Overview

The AD5683RBRMZ-3 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 temperature coefficient of 2 ppm/°C and ±2 LSB maximum integral nonlinearity (INL). The device operates on a single 2.7 V to 5.5 V analog supply 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. The component is housed in a 10-lead MSOP package.

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

Procurement Notes

Verify the specific suffix '-3' against the manufacturer's ordering guide to confirm pinout configuration, as variants within the AD5683R family may differ in available pins such as RESET or SDO. Ensure compatibility with the required 10-lead MSOP footprint and check for RoHS compliance status in current production notices.

Selection Notes

Select this component when a single-channel 16-bit DAC with integrated precision reference is required in a small surface-mount package. It is suitable for applications needing rail-to-rail output swing and independent logic supply voltages down to 1.62 V. Compare with AD5683 (external reference only) if the internal reference is not needed, or consider AD5682R/AD5681R for lower resolution requirements.

Part Context

The AD5683RBRMZ-3 belongs to the nanoDAC+ portfolio, which includes 16-bit, 14-bit, and 12-bit variants. This series is designed to offer high performance in ultrasmall packages, specifically the 2 mm × 2 mm LFCSP and 10-lead MSOP. The 'R' suffix indicates the inclusion of an internal reference, distinguishing it from the standard AD5683 model.

Replacement Considerations

Direct pin-compatible alternatives within the same family include AD5683RBRMZ (standard version) and AD5683RACPZ (LFCSP package). For external reference designs, the AD5683 series offers similar electrical characteristics without the internal reference.
