DAC121C085CIMMX/NOPB

Digital To Analog Converters Overview

The DAC121C085CIMMX/NOPB is a single-channel, 12-bit digital-to-analog converter from Texas Instruments. It features a voltage buffered output and operates on a 2-Wire I2C-compatible interface. 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, 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. It functions within a temperature range of -40°C to +125°C and is housed in a VSSOP-8 package.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm that the VSSOP-8 footprint matches the target PCB layout. Check the latest datasheet for any updates regarding operating conditions or recommended soldering profiles before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with minimal power usage. The I2C interface is ideal for space-constrained designs. Ensure the application voltage falls within the 2.7 V to 5.5 V range. Consider the 6 µs settling time against system speed requirements. Verify thermal management needs for operation up to +125°C.

Digital To Analog Converters Part Context

This part belongs to the DAC121C085 series of micro-power DACs. It is distinct from higher-channel variants like the DAC122S085 or SPI-based models. The CIMM designation indicates the commercial temperature grade and VSSOP-8 package type. The NOPB suffix confirms non-plated lead (lead-free) construction.

Digital To Analog Converters Replacement Considerations

Direct pin-to-pin replacements may be limited due to interface differences. Evaluate DAC121C085 variants with different package options if form factor changes are acceptable. Cross-reference with other TI 12-bit I2C DACs only if interface compatibility and performance margins allow.
