DAC121C085CIMM/NOPB

Digital To Analog Converters Overview

The DAC121C085CIMM/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device features a buffered voltage output with a settling time of 6 µs and supports I2C-compatible 2-wire serial interfaces. Key performance metrics include a maximum sampling rate of 180 kS/s, differential nonlinearity (DNL) of 0.18 LSB, integral nonlinearity (INL) of 2.2 LSB, and gain error of 0.7% FSR. Power consumption is specified at 380 µW. The component functions within an industrial temperature range of -40°C to +125°C and is housed in an 8-pin VSSOP package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure that the ordering information matches the required package type and tape-and-reel configuration. Cross-reference the part number with current datasheet revisions to validate operational parameters before procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with I2C connectivity. Consider the 180 kS/s update rate and 6 µs settling time for dynamic signal requirements. Evaluate the 380 µW power consumption against system battery life constraints. Confirm that the VSSOP-8 package dimensions fit the available PCB real estate.

Digital To Analog Converters Part Context

This device belongs to the DAC121C085 series of micro-power digital-to-analog converters. It shares architectural similarities with other members of the family but is distinguished by its specific 12-bit resolution and I2C interface configuration. The NOPB suffix indicates lead-free construction compliant with RoHS standards.

Digital To Analog Converters Replacement Considerations

The DAC121C085CIMMX/NOPB is a documented alternative variant within the same product line. Verify package and electrical equivalence before substitution.
