AD5683RBCPZ-1RL7

Overview

The AD5683RBCPZ-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 logic support down to 1.62 V. Key specifications include a settling time of 5 µs, low glitch impulse of 0.1 nV-sec, and high drive capability of 20 mA. It utilizes a versatile 3-wire SPI interface compatible with standard modes.

Feature Summary

• 16-bit resolution with ±2 LSB maximum relative accuracy (INL).
• 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.
• Ultrasmall 2 mm × 2 mm, 8-lead LFCSP package.

Applications

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

Procurement Notes

Verify the specific suffix '-1' against official documentation to confirm pinout variations such as VLOGIC or RESET availability. Ensure the reel quantity matches project requirements. Confirm RoHS compliance status through the manufacturer's current datasheet revision.

Selection Notes

Select this component for applications requiring high precision in a minimal footprint. The internal reference eliminates external calibration needs. Verify that the required logic voltage level (down to 1.62 V) is supported by the host system. Consider the 20 mA drive capability for direct load interfacing without additional amplification.

Part Context

This part belongs to the AD5683R/AD5682R/AD5681R series, offering 16-, 14-, and 12-bit resolutions respectively. It shares the same nanoDAC+ architecture and interface protocols. The 'BCPZ' designation indicates the B-grade linearity and LFCSP package. The '-1' suffix typically denotes specific pin configuration options like VLOGIC or RESET presence.

Replacement Considerations

Direct replacements within the same family include AD5683R variants with different suffixes indicating package or pinout changes. For external reference designs, the AD5683 provides identical performance without the internal reference. Cross-model compatibility exists with AD5682R and AD5681R for lower resolution needs.
