DAC121C081CIMK/NOPB

Digital To Analog Converters Overview

The DAC121C081CIMK/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device features an I2C-compatible interface and delivers a buffered voltage output. 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. Nonlinearity specifications are defined by a differential nonlinearity (DNL) of 0.18 LSB and an integral nonlinearity (INL) of 2.2 LSB. The component is housed in a SOT-23-THIN-6 package and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging options. Confirm the manufacturer source is Texas Instruments or an authorized distributor to avoid counterfeit components. Check RoHS status documentation for regulatory compliance requirements in your target market. Ensure the ordering quantity matches the available reel or cut tape configurations provided by the supplier.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is required alongside minimal board space constraints. The I2C interface makes it suitable for systems where pin count is limited compared to SPI alternatives. Consider the 6 µs settling time against application speed requirements. Evaluate the 380 µW power dissipation against total system budget constraints for portable devices.

Digital To Analog Converters Part Context

This device belongs to the DAC121C081 series within the Texas Instruments MicroPwr portfolio. It shares architectural similarities with the 8-bit DAC081C081 and 10-bit variants, offering scalable resolution options. The series emphasizes low power operation and small package sizes, targeting embedded applications where efficiency and size are critical design parameters.

Digital To Analog Converters Replacement Considerations

The DAC121C081CIMK/G4 is a verified equivalent variant with identical electrical characteristics but different lead finish specifications. Other members of the DAC121C family may serve as functional substitutes if resolution and interface compatibility align with system requirements.
