AD5683RACPZ-RL7

Overview

The AD5683RACPZ-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 supports selectable output spans of 0 V to VREF or 0 V to 2 × VREF. The device operates on a single 2.7 V to 5.5 V supply with independent logic compatibility down to 1.62 V. Key electrical parameters include ±2 LSB maximum INL (B Grade), 5 µs settling time, and 1.2 mW power consumption at 3.3 V. It utilizes a versatile 3-wire SPI interface with clock rates 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 relative accuracy (INL) for B Grade devices.
• Integrated low-drift 2.5 V reference with 2 ppm/°C typical temperature coefficient.
• Programmable output span: 0 V to VREF or 0 V to 2 × VREF.
• Ultrasmall 8-lead LFCSP package measuring 2.00 mm × 2.00 mm.

Applications

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

Procurement Notes

Verify the specific suffix 'ACPZ' corresponds to the 8-lead LFCSP package variant when sourcing. Confirm that the 'A' grade designation aligns with system accuracy requirements, as this part number typically denotes the A Grade specification which has higher INL limits compared to the B Grade. Ensure the reel packaging matches production volume needs.

Selection Notes

Select this component for applications requiring high precision in a minimal footprint. The AD5683R includes an internal reference; if external reference buffering is preferred, consider the AD5683 model instead. Verify that the 20 mA drive capability meets load requirements. For designs needing hardware reset or separate logic supply pins, confirm pinout compatibility with the specific sub-model variant included in this order code.

Part Context

This part belongs to the AD5683R/AD5682R/AD5681R series, which are members of Analog Devices' nanoDAC+ family. These devices share a common architecture featuring low power consumption, monotonic operation by design, and a 3-wire serial interface. The AD5683R specifically provides the highest resolution (16-bit) within this particular package configuration grouping.

Replacement Considerations

The AD5683BCPZ-RL7 is a confirmed substitute offering identical functionality but with B Grade accuracy specifications (±2 LSB INL). Other family members like the AD5682R (14-bit) or AD5681R (12-bit) offer lower resolution options within the same package.
