DAC121C085CIMMX

Digital To Analog Converters Overview

The DAC121C085CIMMX is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a voltage-buffered output and operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a 2-Wire I2C-compatible interface for data communication. Key performance metrics include a sampling rate of 180 kS/s, a settling time of 6 µs, and a typical power consumption of 380 µW. Linearity specifications are defined by an INL of 2.2 LSB and a DNL of 0.18 LSB, with a gain error of 0.7% FSR. It is housed in a VSSOP-8 package and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact pinout and electrical characteristics listed in the manufacturer's documentation. Cross-reference the component marking code to distinguish between genuine Texas Instruments products and potential counterfeits during incoming inspection.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with minimal power consumption. The I2C interface makes it suitable for space-constrained designs where fewer GPIO pins are available. Compare the 6 µs settling time against application speed requirements. Consider the VSSOP-8 footprint for PCB layout constraints relative to other packages in the DAC121C085 family.

Digital To Analog Converters Part Context

This part belongs to the DAC121C085 series of micro-power DACs from Texas Instruments. It shares core architectural similarities with variants like the DAC121C085CIMM/NOPB but differs in packaging and reel configuration. The series is characterized by its low cost and efficiency, targeting applications where power budget and board space are critical limiting factors.

Digital To Analog Converters Replacement Considerations

DAC121C085CIMM/NOPB offers identical electrical specifications in a cut-tape or bulk package format.
