AD5683RACPZ-1RL7

Overview

The AD5683RACPZ-1RL7 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 ±2 LSB maximum INL at 16 bits. The device operates on a single 2.7 V to 5.5 V supply with independent 1.62 V logic compatibility. Key specifications include a 5 µs settling time, 20 mA drive capability, and programmable output spans of 0 V to VREF or 0 V to 2 × VREF. It utilizes a versatile 3-wire SPI interface operating up to 50 MHz and is housed in an ultrasmall 2 mm × 2 mm, 8-lead LFCSP package.

Feature Summary

• 16-bit resolution with ±2 LSB maximum integral nonlinearity (INL).
• Integrated low-drift 2.5 V reference (2 ppm/°C typical).
• Programmable output span: 0 V to VREF or 0 V to 2 × VREF.
• High drive capability of 20 mA with rail-to-rail output.

Applications

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

Procurement Notes

Verify the specific suffix 'ACPZ-1RL7' against the manufacturer's current ordering guide to confirm pinout options such as LDAC, VLOGIC, or RESET availability. Ensure the reel packaging quantity matches project requirements. Confirm RoHS compliance status for the specific manufacturing lot before integration into production designs.

Selection Notes

Select this component when high relative accuracy and small footprint are critical. The internal reference eliminates external temperature calibration needs. Verify that the required output swing fits within the 0–VREF or 0–2×VREF programmable ranges. Ensure the host microcontroller supports the 3-wire SPI interface timing constraints for reliable data transfer.

Part Context

This part belongs to the AD5683R/AD5682R/AD5681R/AD5683 nanoDAC+ portfolio. It shares architectural similarities with other members but is distinguished by its 16-bit resolution and integrated reference. The 'R' suffix denotes the inclusion of the internal reference, while 'ACPZ' specifies the LFCSP package and temperature range.

Replacement Considerations

The AD5683BCPZ-RL7 serves as a compatible alternative within the same family. It offers identical 16-bit performance and SPI interface but lacks the internal 2.5 V reference, requiring an external reference source. Pinouts and software commands remain largely consistent between these variants.
