DAC121C081CIMKX/NOPB

Digital To Analog Converters Overview

The DAC121C081CIMKX/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates with an I2C-compatible interface and delivers a buffered voltage output. The device supports analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance metrics include a sampling rate of 180 kS/s and a settling time of 6 µs. Power consumption is specified at 380 µW. Linearity specifications feature a differential nonlinearity (DNL) of 0.18 LSB and an integral nonlinearity (INL) of 2.2 LSB. The gain error is limited to 0.7% of the full-scale range. It functions within a temperature range of -40°C to +125°C and is housed in a SOT-23-THIN-6 package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm it denotes the tape-and-reel packaging variant rather than a functional difference. Ensure the component matches the standard DAC121C081CIMK/NOPB electrical specifications. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is required alongside a compact SOT-23-THIN-6 footprint. The I2C interface minimizes pin count compared to SPI alternatives. Verify that the 180 kS/s update rate meets the application bandwidth requirements. Check that the 2.7 V to 5.5 V supply range aligns with the system power rails.

Digital To Analog Converters Part Context

This part belongs to the DAC121C081 family of micro-power digital-to-analog converters. It shares core specifications with the DAC121C081CIMK/NOPB but differs in packaging format. The series is designed for cost-sensitive and space-constrained designs requiring moderate precision and low power usage.

Digital To Analog Converters Replacement Considerations

The DAC121C081CIMK/NOPB serves as a direct pin-compatible alternative if reel packaging is not required. Other members of the DAC121C081 family may offer different package options or automotive qualifications.
