DAC128S085CISQ/NOPB

Digital To Analog Converters Overview

The DAC128S085CISQ/NOPB is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor string architecture with eight independent voltage-buffered outputs capable of rail-to-rail swing. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It supports serial interfaces including SPI, QSPI, Microwire, and DSP modes via a 3-wire connection. Key performance metrics include a settling time of 6 µs, a typical operating current of 650 µA, and power consumption of 1.95 mW. Nonlinearity specifications are defined by a DNL of 0.15 LSB and an INL of ±2 LSB.
