DAC124S085CISD

Digital To Analog Converters Overview

The DAC124S085CISD is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates with analog and digital supply voltages ranging from 2.7 V to 5.5 V. The device supports serial interfaces including SPI, Microwire, and DSP standards. Key electrical parameters include a sampling rate of 2.5 MS/s per channel, a settling time of 6 µs, and a power consumption of 1.1 mW. Differential nonlinearity is specified at 0.2 LSB, while integral nonlinearity is +/- 2.4 LSB. Gain error is limited to 1% FSR. The component is housed in a WSON-10 package and functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the suffix /NOPB when sourcing components to ensure compliance with lead-free manufacturing standards. Confirm the specific package variant matches the design requirements, as the base model may correspond to different packaging options such as tape-and-reel or cut tape configurations depending on distributor availability.

Digital To Analog Converters Selection Notes

Select this component when designing circuits that require four independent 12-bit outputs in a minimal footprint. Ensure the host microcontroller supports the required serial clock speeds and interface modes. Verify that the system power supply remains stable within the 2.7 V to 5.5 V range to maintain specified linearity and accuracy performance across the full industrial temperature spectrum.

Digital To Analog Converters Part Context

This device belongs to the DAC124S085 family of micro-power quad DACs from Texas Instruments. It shares functional similarities with other members like the DAC124S085CIMM but differs in package type. The series is designed for cost-sensitive applications needing multiple channels without external buffering components.
