+title: Texas Instruments DAC8163 family of DACs
+
+description:
+  The DAC756x, DAC816x, and DAC856x devices are low-power, voltage-output,
+  dual-channel, 12-, 14-, and 16-bit digital-to-analog converters (DACs),
+  respectively. These devices include a 2.5-V, 4-ppm/°C internal
+  reference, giving a full-scale output voltage range of 2.5 V or 5 V.
