Overview
The DAC80004IPWR from Texas Instruments is a highly accurate, low-power, voltage-output, quad-channel 16-bit digital-to-analog converter (DAC). This device is part of the DACx0004 series, which includes 16-, 14-, and 12-bit versions. The DAC80004IPWR is designed to offer excellent linearity, with an integral non-linearity (INL) and differential non-linearity (DNL) of less than 1 LSB (Max). It features a versatile 4- or 3-wire serial interface compatible with SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces, operating at clock rates up to 50 MHz. The device is suitable for a wide range of applications, including portable and battery-operated equipment, due to its low power consumption and compact packaging.
