AD5682RBCPZ-RL7

Overview

The AD5682RBCPZ-RL7 is a single-channel, 14-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 operates on a single 2.7 V to 5.5 V supply. The device guarantees monotonicity with ±1 LSB DNL and ±1 LSB INL. It utilizes a versatile 3-wire SPI interface supporting clock rates up to 50 MHz. Key performance metrics include a settling time of 5 µs, low glitch impulse of 0.1 nV-sec, and high drive capability of 20 mA. Power consumption is 1.2 mW at 3.3 V in normal mode.

Feature Summary

• 14-bit resolution with ±1 LSB maximum INL and DNL
• Internal 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 configuration against the manufacturer's ordering guide to confirm pinout options such as LDAC, VLOGIC, or RESET availability. Ensure the reel packaging matches production requirements. Confirm RoHS compliance status for the specific batch before integration into manufacturing workflows.

Selection Notes

Select this component when a single-channel 14-bit DAC with high relative accuracy is required. The internal reference eliminates external components for standard applications. Consider the selectable gain setting (1x or 2x) to match the desired output voltage range. Verify that the 3-wire SPI interface timing meets the system controller's capabilities.

Part Context

This part belongs to the AD5683R/AD5682R/AD5681R series, which shares a common architecture but differs in resolution. The AD5682R provides 14-bit precision, positioned between the 12-bit AD5681R and the 16-bit AD5683R. All members offer similar power profiles and interface compatibility within the nanoDAC+ family.

Replacement Considerations

Direct functional substitutes within the same package include the AD5683R (16-bit) and AD5681R (12-bit). For higher channel counts, consider the AD5668 series. Verify pin compatibility if replacing with MSOP variants or devices with different reference configurations.
