DAC122S085CIMM

Digital To Analog Converters Overview

The DAC122S085CIMM is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes a resistor string architecture and features voltage buffered outputs. The device supports serial interfaces including SPI, QSPI, Microwire, DSP, and 3-Wire configurations. It operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance parameters include a settling time of 6 µs, a differential nonlinearity (DNL) of 0.2 LSB, and an integral nonlinearity (INL) of +/- 2.4 LSB. The gain error is specified at 1% FSR. The component is housed in a 10-pin MSOP package and functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm package type and environmental rating. Ensure the ordering part number matches the required pinout and thermal specifications. Cross-reference manufacturer datasheets for any recent revisions or obsolescence notices before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit precision is required in a compact surface-mount package. Consider the 6 µs settling time and external reference requirement during circuit design. Evaluate the MSOP-10 footprint constraints against available PCB space and thermal dissipation needs.

Digital To Analog Converters Part Context

This model belongs to the DAC122S085 series, which includes variants such as the DAC122S085CISD/NOPB and DAC122S085CIMMX/NOPB. These parts share identical electrical characteristics but differ in physical packaging, specifically between MSOP and WSON form factors. The series is designed for low-power, space-constrained digital-to-analog conversion tasks.

Digital To Analog Converters Replacement Considerations

The DAC122S085CIMM/NOPB serves as a direct replacement with RoHS compliance. Verify pin compatibility and package dimensions when substituting with other series members like the CISMX variant.
