Overview
The AD5660CRMZ-2 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 4.5 V to 5.5 V supply and features an internal 2.5 V reference with a temperature coefficient of 5 ppm/°C, yielding a full-scale output range of 0 V to VDD. The device guarantees monotonicity by design and includes a power-on reset circuit that initializes the output to 0 V. Key electrical parameters include a settling time of 8 µs, ±1 LSB differential nonlinearity, and a typical supply current of 0.55 mA.
Feature Summary
- Integrated 2.5 V precision reference with 5 ppm/°C temperature coefficient
- Rail-to-rail buffered analog output amplifier
- Versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards
- Power-down mode reduces current consumption to 480 nA at 5 V
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix '2' confirms the inclusion of the internal 2.5 V reference and the 4.5 V to 5.5 V operating voltage range. Confirm the package designation matches the MSOP-8 form factor required for the target PCB layout. Ensure compatibility with the system's logic voltage levels before integration.
Selection Notes
Select this component when a 16-bit resolution and high accuracy are required within a single-channel configuration. The internal 2.5 V reference eliminates the need for external components, simplifying the design. Verify that the application requires a rail-to-rail output swing and can accommodate the specified 4.5 V minimum supply voltage.
Part Context
This part belongs to the AD5620/AD5640/AD5660 nanoDAC series, which offers 12-, 14-, and 16-bit resolutions respectively. The AD5660 variant provides the highest resolution in the family. The CRMZ-2 suffix indicates the specific reference voltage configuration and packaging style compared to other members like the AD5660CRMZ-1 or AD5660CRMZ-3.
Replacement Considerations
The AD5662 is listed as a related device offering similar 16-bit performance but requires an external reference. Other family members such as the AD5640 or AD5620 provide lower resolutions (14-bit and 12-bit) and may serve as alternatives if resolution requirements are less stringent.
