DAC081C085CIMM/NOPB

Digital To Analog Converters Overview

The DAC081C085CIMM/NOPB is an 8-bit digital-to-analog converter from Texas Instruments, housed in an 8-VSSOP package. It features a single 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 4.5 ns, and a power consumption of 380 uW. Linearity specifications are defined by a differential nonlinearity (DNL) of +/- 0.1 LSB and an integral nonlinearity (INL) of +/- 0.6 LSB. The gain error is specified at 0.7% FSR. It functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates a low-power 8-bit DAC with a buffered voltage output for direct drive applications.
• Utilizes an I2C-compatible serial interface to minimize pin count and simplify system connectivity.
• Designed for cost-optimized implementations requiring small form factor solutions.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the VSSOP-8 package dimensions match PCB footprint requirements. Ensure the I2C address configuration aligns with system bus constraints. Check for any recent product lifecycle notices regarding availability or obsolescence status before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy needs. The I2C interface makes it suitable for systems with limited GPIO resources. Consider the 380 uW power consumption for battery-operated designs. Verify that the 2.7 V to 5.5 V supply range covers the system's available voltage rails. The wide industrial temperature range supports operation in harsh environments.

Digital To Analog Converters Part Context

This part belongs to the DAC081C085 series of micro-power DACs. It shares architectural similarities with other members like the DAC081C081 but differs in interface type and packaging. The CIMM suffix denotes the commercial temperature grade and VSSOP-8 package variant. It serves as a compact solution for single-channel conversion tasks within the broader Texas Instruments data converter portfolio.

Digital To Analog Converters Replacement Considerations

The DAC081C085CIMM/NOPB is functionally equivalent to the DAC081C085CIMM. Other variants in the same family include the DAC081C085CIMMX/NOPB. These parts share identical electrical characteristics and pinouts, allowing for potential substitution if package compatibility is confirmed.
