Overview
The DAC70004IPWR, part of the DACx0004 family from Texas Instruments, is a highly accurate, low-power, quad-channel digital-to-analog converter (DAC). This device is available in 14-bit resolution and is designed to offer excellent linearity and low power consumption, making it ideal for various applications including portable instrumentation, PLC analog output modules, and data acquisition systems. The DAC70004IPWR features a wide power-supply range of 2.7 V to 5.5 V and incorporates a power-on-reset circuit that ensures the DAC output powers up at zero scale or mid scale. It also includes a versatile 4- or 3-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP interfaces.
