Overview
The DAC8574IPWR is a low-power, quad-channel, 16-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device features a buffered voltage output and is designed for applications requiring high precision and low power consumption. It operates with an I2C compatible two-wire serial interface, supporting high-speed modes up to 3.4 Mbps. The DAC8574IPWR is particularly suited for portable battery-operated equipment due to its micropower operation and power-down capabilities.
