Overview
The DAC70004IPW, produced by Texas Instruments, is a highly accurate, low-power, voltage-output, quad-channel 14-bit digital-to-analog converter (DAC). This device is part of the DACx0004 family, which includes 16-, 14-, and 12-bit versions. The DAC70004IPW is designed to offer excellent linearity with less than 1 LSB (Max) INL/DNL and is ensured monotonic by design. It features an internal reference buffer and a power-on-reset circuit that ensures the DAC output powers up at zero scale or mid scale. The device is suitable for portable, battery-operated equipment due to its low current consumption of 1 mA per channel and a power-down feature that reduces current to typically 3 µA at 5 V.
