AD5660CRM-1REEL7

Overview

The AD5660CRM-1REEL7 is a single-channel, 16-bit digital-to-analog converter (DAC) from the nanoDAC family. It features an internal 1.25 V reference with a temperature coefficient of 5 ppm/°C, providing a full-scale output range of 2.5 V. The device operates on a single 2.7 V to 3.3 V supply and includes a power-on reset circuit that initializes the output to 0 V. It supports serial interfaces including SPI, QSPI, Microwire, and DSP standards with clock rates up to 30 MHz. The DAC offers rail-to-rail output swing, low power consumption, and three software-selectable power-down modes.

Feature Summary

• Integrated precision voltage reference with low temperature drift
• Rail-to-rail buffered analog output amplifier
• Versatile serial interface compatible with multiple communication protocols
• Power-on reset ensures defined initial output state

Applications

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

Procurement Notes

Verify the specific suffix '1' indicates the 1.25 V internal reference configuration. Confirm the package type matches the design requirements, as this part number typically corresponds to the MSOP or LFCSP variant depending on the manufacturer's specific ordering code structure. Ensure compatibility with the 2.7 V to 3.3 V supply voltage range for the target application.

Selection Notes

Select this component when a high-resolution 16-bit DAC is required in a compact footprint with integrated reference capabilities. It is suitable for applications demanding low power consumption and precise voltage generation within a limited supply voltage range. Consider the settling time and linearity specifications against the system's accuracy requirements.

Part Context

This device belongs to the AD5620/AD5640/AD5660 nanoDAC family, which provides 12-, 14-, and 16-bit resolution options. The AD5660 specifically offers 16-bit performance with guaranteed monotonicity by design. The family shares common pinouts and interface protocols, facilitating design scalability across different resolution needs.

Replacement Considerations

The AD5660ARJZ-1REEL7 serves as a parametric equivalent with similar electrical characteristics but utilizes a SOT-23-8 package instead of the MSOP/LFCSP form factor. Designers must verify pinout compatibility and thermal performance differences between packages before substitution.
