Product Overview
DAC80502DRXR provides two high-resolution voltage outputs from a tiny 2.5 mm-class WSON. Both channels share an integrated low-drift reference and can be configured for 1.25 V, 2.5 V or 5 V buffered ranges.
Sixteen-bit linearity makes reference noise, grounding, thermal gradients and output loading materially important. The component can provide 65,536 codes, but the system only benefits if the reference and PCB preserve that precision.
The selectable SPI/I²C interface eases platform reuse while the DRXR suffix identifies the 3000-piece leadless production reel.

Functional Highlights
Dual 16-bit outputs support matched precision set points
Two bias, calibration or source-control nodes can share one reference and one compact package.
Internal reference reduces channel-to-channel gain uncertainty from separate references
Both outputs derive their scale from the same 2.5 V reference architecture, useful when relative tracking matters.
Design Considerations
- Use careful ground/reference decoupling appropriate to 16-bit resolution.
- Manage WSON exposed-pad soldering and thermal gradients in production.
- Choose output range to maximize code utilization without clipping required headroom.
