+description: |
+ The AD5710R (16-bit) and AD5711R (12-bit) are 8-channel, low-power,
+ configurable current/voltage output digital-to-analog converters (DACs) with
+ an on-chip 2.5V, 3ppm/°C reference. Each channel can be independently
+ configured as a voltage output (0V to VREF or 0V to 2xVREF) or a current
+ output (0mA to 50mA). These devices operate from a single 2.7V to 5.5V
+ supply and are guaranteed monotonic by design.
+ Datasheet can be found here:
+ https://www.analog.com/media/en/technical-documentation/data-sheets/ad5711r-ad5710r.pdf
