DAC161S055CISQX

Digital To Analog Converters Overview

The DAC161S055CISQX is a discontinued 16-bit precision digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with a buffered voltage output and supports a 4-wire SPI interface operating at clock frequencies up to 20 MHz. The device operates on an analog supply voltage ranging from 2.7 V to 5.25 V and a separate digital I/O supply from 1.7 V to 5.25 V. Key performance metrics include a typical settling time of 5 µs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1.1 LSB maximum. It is housed in a 16-pin WQFN package.
