Overview
The DAC8571IDGKR is a 16-bit, low-power, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. It features an I²C compatible two-wire serial interface and is designed for applications requiring high precision and low power consumption. The DAC is particularly suited for portable battery-operated equipment due to its micropower operation and small 8-lead MSOP package. It operates over a wide temperature range of -40°C to 105°C and supports standard, fast, and high-speed modes of I²C operation up to 3.4 MHz serial clock speeds.
