AD5660CRMZ-3

Overview

The AD5660CRMZ-3 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 temperature coefficient of 5 ppm/°C, providing a full-scale output range of 5 V. The device operates on a single 4.5 V to 5.5 V supply and supports serial interfaces including SPI, QSPI, Microwire, and DSP standards at clock rates up to 30 MHz. Key electrical parameters include a settling time of 8 µs, ±1 LSB differential nonlinearity, and power-down current as low as 480 nA at 5 V.

Feature Summary

• 16-bit resolution with guaranteed monotonicity by design
• Internal 2.5 V precision reference (5 ppm/°C)
• Power-on reset to midscale output
• Rail-to-rail output amplifier

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix 'CRMZ-3' against the manufacturer's ordering guide to confirm the package type and internal reference configuration. Ensure the application circuit supports the required 4.5 V to 5.5 V supply range for proper operation of the -2/-3 variants.

Selection Notes

Select this part when a 5 V full-scale output is required with an integrated reference. The -3 suffix indicates a midscale power-on reset state; choose the -1 or -2 suffix if a zero-volt power-on reset is needed instead.

Part Context

This component belongs to the AD5620/AD5640/AD5660 nanoDAC series. It shares the same core architecture and pinout with the AD5660CRMZ-1 (1.25 V ref) and AD5660CRMZ-2 (2.5 V ref), differing primarily in the internal reference voltage and resulting power-on reset behavior.

Replacement Considerations

The AD5662 serves as a related device offering external reference options in similar packages. Direct substitution requires verifying that the system can accommodate an external reference source if replacing the integrated reference functionality.
