AD5663RBCPZ-3R2

Overview

The AD5663RBCPZ-3R2 is a dual 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family by Analog Devices. It operates on a single 2.7 V to 5.5 V supply and features an integrated 1.25 V reference with a 5 ppm/°C temperature coefficient, yielding a 2.5 V full-scale output range. The device guarantees monotonicity by design and includes a power-on reset circuit that ensures outputs start at 0 V. It supports serial interfaces up to 50 MHz, including SPI, QSPI, MICROWIRE, and DSP standards, and offers per-channel power-down modes for low-power applications.

Feature Summary

• Dual 16-bit resolution with rail-to-rail output capability
• Integrated 1.25 V, 5 ppm/°C on-chip reference
• Guaranteed monotonic operation without missing codes
• Versatile 3-wire serial interface compatible with standard protocols

Applications

• Process control systems
• Portable battery-powered instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix '3R2' against the manufacturer's official ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with the -40°C to +105°C industrial temperature range requirements for the target application environment.

Selection Notes

Select this component when dual-channel precision is required in a minimal footprint. The internal 1.25 V reference simplifies design by eliminating external reference components, provided the 2.5 V full-scale output meets system voltage constraints. Consider the 4.5 µs maximum settling time for high-speed data acquisition needs.

Part Context

This part belongs to the AD5623R/AD5643R/AD5663R nanoDAC family, which shares pin compatibility across 12-, 14-, and 16-bit resolutions. The AD5663R variant specifically provides the highest resolution within this low-power series, utilizing either MSOP or LFCSP packaging options.

Replacement Considerations

Pin-compatible alternatives within the same family include the AD5643R (14-bit) and AD5623R (12-bit). For external reference versions, the AD5663 is available, though it lacks the integrated reference.
