Overview
The AD5687RBRUZ-RL7 is a dual, 12-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device supports a 50 MHz SPI interface with readback or daisy-chain capabilities and includes user-selectable gain settings of 1 or 2 via the GAIN pin. Key performance metrics include ±1 LSB maximum INL, ±1 LSB DNL, and a settling time of 5 µs. It offers low power consumption of 3.3 mW at 3 V and incorporates power-down modes reducing current to 4 µA.
Feature Summary
- Dual-channel 12-bit resolution with ±1 LSB INL/DNL accuracy
- Integrated 2.5 V reference with 2 ppm/°C temperature coefficient
- User-selectable gain of 1 or 2 for full-scale output adjustment
- 50 MHz SPI interface with 1.8 V logic compatibility
Applications
- Optical transceivers
- Base station power amplifiers
- Process control PLC I/O cards
- Industrial automation systems
- Data acquisition systems
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt, as the TSSOP-16 variant is sensitive to mechanical stress during handling. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to prevent soldering defects during assembly.
Selection Notes
Select this model when 12-bit resolution and high relative accuracy are required alongside low power consumption. The internal reference eliminates the need for external components, simplifying board layout. Verify that the application logic voltage falls within the 1.62 V to 5.5 V range for proper SPI interface operation.
Part Context
This part belongs to the AD5687R series, which shares architectural similarities with the 16-bit AD5689R. Both devices utilize the same nanoDAC+ architecture and package options but differ in resolution and specific accuracy grades. The RL7 suffix indicates reel packaging for automated surface-mount assembly.
Replacement Considerations
The AD5687BRUZ serves as a non-RoHS compliant alternative within the same family. For applications requiring higher resolution, the AD5689RBRUZ-RL7 provides equivalent functionality with 16-bit precision.
