Overview
The AD5660BRJZ-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 utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 20 MHz at this voltage range. The DAC offers rail-to-rail buffered voltage output, guaranteed monotonicity by design, and low power consumption with three software-selectable power-down modes.
Feature Summary
- Integrated precision 1.25 V reference source
- Rail-to-rail buffered analog output
- Software-selectable power-down functionality
- Power-on reset to zero scale
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 internal 1.25 V reference configuration during procurement. Confirm the package type matches the required footprint, as the BRJZ designation corresponds to the MSOP package. Ensure the operating voltage environment remains within the 2.7 V to 3.3 V range specified for this reference variant.
Selection Notes
Select this component when a single-channel 16-bit resolution is required with minimal external components. The internal reference eliminates the need for external voltage references, simplifying board layout. Consider the MSOP package dimensions if space constraints are critical. Verify that the 2.7 V to 3.3 V supply range aligns with the system's power architecture.
Part Context
This part belongs to the AD5620/AD5640/AD5660 nanoDAC family, which shares pin compatibility across 12-bit, 14-bit, and 16-bit resolutions. The AD5660 variant provides the highest resolution in this series. The 'BRJZ' suffix denotes the B grade accuracy and MSOP package, while '-1' specifies the internal 1.25 V reference option.
Replacement Considerations
Direct replacements include other AD5660 variants with different packages or reference voltages, such as AD5660ARJZ-2REEL7. Cross-model substitutes like the AD5662 offer similar performance but require an external reference.
