Digital to Analog Converters

DAC084S085CISD Description

The DAC084S085CISD is an 8-bit, quad-channel digital-to-analog converter (DAC) manufactured by Texas Instruments. Designed for precision voltage output applications, this IC integrates four DACs in a compact 10-WSON package, making it suitable for space-constrained designs. Operating with a 2.7V to 5.5V analog and digital supply range, it supports flexible power configurations while delivering stable performance. The DAC084S085CISD employs a string DAC architecture and features an SPI/DSP-compatible serial interface, ensuring seamless integration with microcontrollers and digital signal processors. Although marked as obsolete, it remains a reliable choice for legacy systems due to its low INL/DNL (±0.14 LSB, +0.04 LSB max) and fast 4.5µs settling time.
