+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 2 x VREF) 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
