DAC121S101CIMM

Digital To Analog Converters Overview

The DAC121S101CIMM is a single-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Texas Instruments. It features a rail-to-rail output stage and operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device supports serial interfaces including SPI, Microwire, and QSPI, with a maximum sampling rate of 1.8 MS/s. Key performance metrics include a settling time of 8 µs, an Integral Nonlinearity (INL) of ±2.6 LSB, and a Differential Nonlinearity (DNL) of 1 LSB. Power consumption is typically 640 µW. It is housed in an 8-pin VSSOP package and functions within an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Rail-to-rail output capability allows full-scale signal swing across the entire supply voltage range.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements if mandated by the target application. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times prior to procurement planning.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with rail-to-rail output capabilities. It is appropriate for designs needing a 1.8 MS/s update rate while maintaining low power consumption. Consider the VSSOP-8 package size constraints and the operating temperature range of -40°C to +125°C during system integration.

Digital To Analog Converters Part Context
