DAC121C081CISDX/NOPB

Digital To Analog Converters Overview

The DAC121C081CISDX/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a serial I2C-compatible interface and delivers a buffered voltage output. The device operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance specifications include a sampling rate of 180 kS/s, a settling time of 6 µs, and a maximum power consumption of 380 µW. Non-linearity errors are specified with an Integral Nonlinearity (INL) of 2.2 LSB and a Differential Nonlinearity (DNL) of 0.18 LSB. The component is housed in a WSON-6 package and supports an industrial operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'DX' against the official datasheet to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact package variant and temperature grade required for the target application environment. Cross-reference manufacturer documentation for any recent lifecycle or compliance updates.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution conversion is needed within a minimal footprint. Compare the 12-bit resolution and 180 kS/s speed against application bandwidth requirements. Evaluate the WSON-6 package dimensions against available PCB space constraints relative to other packages in the DAC121C081 family.

Digital To Analog Converters Part Context

This part belongs to the DAC121C081 series of micro-power digital-to-analog converters. It shares core electrical characteristics with variants such as the DAC121C081CISD/NOPB and DAC121C081CIMK/NOPB, differing primarily in package type and manufacturing lot coding. The series is designed for cost-sensitive, space-constrained embedded systems.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include DAC121C081CISD/NOPB for WSON-6 packaging or DAC121C081CIMK/NOPB for TSOT-23-6 packaging. Verify pinout compatibility and thermal performance before substituting across different package types.
