AD5664RBCPZ-3REEL7

Overview

The AD5664RBCPZ-3REEL7 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply and features an on-chip 1.25 V reference with a temperature coefficient of 5 ppm/°C, providing a full-scale output range of 2.5 V. The device includes a power-on reset circuit that ensures outputs start at zero scale. It utilizes a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 50 MHz. The part is guaranteed monotonic by design and offers per-channel power-down modes.

Feature Summary

• Quad 16-bit resolution with rail-to-rail output swing
• On-chip 1.25 V reference (5 ppm/°C) for 2.5 V full-scale range
• Power-on reset to zero scale
• Per-channel power-down reducing current to 480 nA at 5 V

Applications

• Process controls
• Data acquisition systems
• Portable battery-powered instruments
• Digital gain and offset adjustment
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix '3' indicates the internal 1.25 V reference configuration during procurement. Confirm the package type matches the required footprint, as this model designation typically corresponds to the LFCSP_WD package. Ensure compatibility with the 2.7 V to 5.5 V supply voltage range for the target application environment.

Selection Notes

Select this component when a quad channel DAC with high precision (16-bit) and low power consumption is required. The internal 1.25 V reference makes it suitable for applications where external references are undesirable or space is limited. Consider the 50 MHz serial interface speed if high update rates are necessary. Verify that the 2.5 V full-scale output range meets the system requirements.

Part Context

This part belongs to the nanoDAC family, which includes the AD5624R (12-bit) and AD5644R (14-bit). All members share pin compatibility and similar feature sets, differing primarily in resolution and reference options. The AD5664R variant provides the highest resolution within this specific quad-channel group.

Replacement Considerations

The AD5664RBCPZ-5REEL7 is a direct replacement if a 5 V full-scale range (using the internal 2.5 V reference) is acceptable instead of the 2.5 V range provided by the -3 suffix.
