Overview
The AD5660CRMZ-1 is a single-channel, 16-bit buffered voltage output 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 ensures the output powers up to 0 V. It supports serial interfaces including SPI, QSPI, Microwire, and DSP standards at clock rates up to 30 MHz.
Feature Summary
- 16-bit resolution with guaranteed monotonicity by design
- Internal 1.25 V precision reference yielding a 2.5 V full-scale output range
- Power-on reset circuit forces output to 0 V upon initialization
- Low power consumption: 2.5 mW active, 1 µW in power-down mode
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific ordering suffix 'CRMZ-1' against the manufacturer's official documentation to confirm the package type, temperature grade, and reference configuration. Ensure compatibility with the required 2.7 V to 3.3 V supply voltage for this specific variant.
Selection Notes
Select the AD5660CRMZ-1 when a 16-bit resolution and a 2.5 V output span are required within a low-power constraint. This part is suitable for designs needing a rail-to-rail output amplifier and an integrated reference, eliminating the need for external components. Verify that the system logic levels align with the specified input voltage requirements.
Part Context
This component belongs to the AD5620/AD5640/AD5660 nanoDAC series. The '-1' suffix indicates the inclusion of an internal 1.25 V reference, distinguishing it from variants with different reference voltages or external reference inputs. It shares the same core architecture as the 12-bit AD5620 and 14-bit AD5640 but offers higher resolution.
Replacement Considerations
Direct replacements include other members of the AD5660 family such as AD5660CRMZ-2 or AD5660CRMZ-3, provided the application can accommodate their respective 5 V full-scale output ranges. For lower resolution needs, the AD5640 or AD5620 may be considered if 16-bit accuracy is not strictly required.
