Overview
The AD5660CRM-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 power supply ranging from 2.7 V to 3.3 V and supports clock rates up to 30 MHz via a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. It guarantees 16-bit monotonicity by design and incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V.
Feature Summary
- Integrated precision 1.25 V reference with low temperature drift
- Rail-to-rail analog output amplifier for maximum dynamic range
- Software-selectable power-down modes reducing current consumption significantly
- Power-on reset function ensuring safe zero-voltage startup
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and package type. Ensure the selected variant matches the required operating voltage range and reference configuration for your application design.
Selection Notes
Select this component when a high-resolution, low-power single-channel DAC is required. The integrated 1.25 V reference simplifies board layout by eliminating external precision references. Verify that the system logic levels are compatible with the specified input voltage thresholds for reliable serial communication.
Part Context
This part belongs to the AD5620/AD5640/AD5660 nanoDAC family, which offers 12-, 14-, and 16-bit resolutions respectively. The -1 suffix indicates the inclusion of an internal 1.25 V reference, distinguishing it from variants with 2.5 V references or external reference inputs. These devices share common architectural features such as the resistor string DAC core and serial interface logic.
Replacement Considerations
Direct replacements within the same family include the AD5660CRMZ-1 and AD5660ARMZ-1, which offer identical electrical specifications but differ in package style. Cross-family alternatives like the AD5662 require external references and may have different pin configurations.
