DAC121C081CISDX

Digital To Analog Converters Overview

The DAC121C081CISDX is a 12-bit micro power digital-to-analog converter manufactured by Texas Instruments. It features a single buffered voltage 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 electrical specifications include a sampling rate of 180 kS/s, a settling time of 6 µs, and a maximum power consumption of 380 µW. Nonlinearity performance is characterized by a differential nonlinearity (DNL) of 0.18 LSB and an integral nonlinearity (INL) of 2.2 LSB. The gain error is specified at 0.7% FSR. It is housed in a WSON-6 package and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'DX' against the manufacturer's current datasheet to confirm availability status, as this suffix often denotes tape-and-reel packaging which may differ from cut-tape options. Ensure the component matches the required RoHS compliance standards for your region. Cross-reference the full part number including the '/NOPB' designation if lead-free certification is mandatory for your assembly process. Confirm the manufacturing date code aligns with your project timeline requirements.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is necessary alongside minimal power usage in a small form factor. Compare DNL and INL specifications against application tolerance levels to ensure signal integrity. Verify that the I2C address configuration meets system bus requirements. Consider the WSON-6 thermal characteristics if multiple devices are placed in close proximity on the board.

Digital To Analog Converters Part Context

This part belongs to the DAC121C081 family of micro power DACs from Texas Instruments. It shares architectural similarities with other members like the DAC121C081CISD/NOPB but differs in packaging or reel specifications. The series is designed to provide cost-effective solutions for general-purpose analog output needs without sacrificing precision.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include DAC121C081CISD/NOPB. Check for pin compatibility and identical electrical parameters before swapping. Alternative packages such as SOT-23-THIN-6 variants exist but require layout adjustments.
