DAC121S101CIMKX

Digital To Analog Converters Overview

The DAC121S101CIMKX/NOPB is a 12-bit micro power digital-to-analog converter manufactured by Texas Instruments. It features a single channel with a sampling rate of 1.8 MS/s and a settling time of 8 µs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It utilizes a serial interface compatible with SPI, DSP, Microwire, and QSPI standards. The output type is voltage buffered with rail-to-rail capability. Key performance metrics include a differential nonlinearity (DNL) of 1 LSB and an integral nonlinearity (INL) of +/- 2.6 LSB. Power consumption is specified at 640 µW. 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 when sourcing, as it indicates lead-free status and RoHS compliance. Confirm the specific package variant matches the PCB footprint requirements. Check for automotive qualification if the application requires AEC-Q100 certification, noting that standard commercial versions may differ from qualified variants. Ensure the ordering quantity aligns with the manufacturer's standard reel sizes.

Digital To Analog Converters Selection Notes

Select this component when a balance between 12-bit resolution and ultra-low power consumption is required. Compare DNL and INL specifications against system accuracy needs, as these parameters define linearity performance. Consider the 1.8 MS/s speed limit for bandwidth requirements. Evaluate the SOT-23-THIN-6 package size against available board space constraints relative to other pinout options in the series.

Digital To Analog Converters Part Context

This device belongs to the DAC121S101 family of micro power digital-to-analog converters. It shares architectural similarities with the DAC081S101 and DAC101S101 models, differing primarily in resolution. The family is characterized by its small footprint and ability to operate from a single low-voltage supply. It serves as a successor to older generation serial DACs, offering improved power efficiency and integrated buffering.

Digital To Analog Converters Replacement Considerations

Direct replacements include the DAC121S101CIMK/NOPB which shares identical electrical characteristics and pinout. Verify if automotive-grade variants like DAC121S101QCMK/NOPB are required for extended temperature or reliability standards. Cross-reference with DAC101S101 or DAC081S101 models only if reduced resolution is acceptable for the application.
