AD5660CRM-2REEL7

Overview

The AD5660CRMZ-2REEL7 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 3 V or 5 V supply and includes a power-on reset circuit that ensures the output powers up to zero volts. It supports serial interfaces compatible with SPI, QSPI, Microwire, and DSP standards, with clock rates up to 30 MHz. The DAC guarantees monotonicity by design and offers low power consumption, including a power-down mode reducing current to 480 nA at 5 V.

Feature Summary

• 16-bit resolution with guaranteed monotonic operation
• Internal 2.5 V reference with 5 ppm/°C temperature coefficient
• Rail-to-rail output amplifier with 10 µs settling time
• Software-selectable power-down modes reducing current to 480 nA

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 'CRMZ-2REEL7' against the manufacturer's ordering guide to confirm package type (MSOP), temperature grade, and reel quantity. Confirm the '-2' designation corresponds to the internal 2.5 V reference configuration as specified in the datasheet.

Selection Notes

Select this component for applications requiring high precision with minimal external components. The internal 2.5 V reference eliminates the need for external voltage references. Ensure the system logic levels are compatible with the 3 V or 5 V operating voltage range and that the serial interface timing meets the 30 MHz maximum clock rate requirement.

Part Context

This part belongs to the AD5620/AD5640/AD5660 nanoDAC family, which shares similar pinouts and functional blocks but varies in resolution (12-bit, 14-bit, and 16-bit respectively). The AD5660 provides the highest resolution within this group, offering 16-bit accuracy for demanding analog output applications.

Replacement Considerations

The AD5662 is listed as a related device with similar packaging options but requires an external reference. Verify if the internal reference capability is critical for the replacement; if so, the AD5660 remains the appropriate choice over the AD5662.
