Overview
The DAC101C081CIMKX/NOPB is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. This device operates from a 2.7 V to 5.5 V supply and features a rail-to-rail output amplifier with a settling time of 6 microseconds. It is designed for low power consumption, typically consuming 132 µA at 5.0 V, making it suitable for battery-operated equipment. The DAC101C081 is available in 6-lead SOT and WSON packages and supports three address options via pin selection, allowing multiple devices to be connected on the same 2-wire bus.
