Overview
The DAC6311IDCKTG4 is a 10-bit, low-power, single-channel, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is part of the DACx311 family, which includes 8-bit, 10-bit, and 12-bit resolutions. The DAC6311 is fabricated using Texas Instruments' proprietary HPA07 process technology and features a string DAC followed by an output buffer. It is designed for microPower operation, consuming only 80 μA at 2.0 V and as low as 0.5 μA in power-down mode at 5 V. This makes it an excellent choice for portable, battery-operated applications and other power-sensitive designs.
