DAC121S101QCMKX/NOPB

Digital To Analog Converters Overview

The DAC121S101QCMKX/NOPB is a 12-bit, single-channel voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and consumes approximately 177 µA at 3.6 V. The device features a rail-to-rail output amplifier and supports high-speed serial interfaces including SPI, QSPI, Microwire, and DSP modes with clock rates up to 30 MHz. Key electrical specifications include a settling time of 8 µs, a sampling rate of 1.8 MS/s, differential nonlinearity (DNL) of 1 LSB, integral nonlinearity (INL) of ±2.6 LSB, and gain error of 1% FSR. It is housed in a SOT-23-THIN-6 package and qualified for automotive applications under AEC-Q100 standards.

Digital To Analog Converters Feature Summary

• Rail-to-rail voltage output capability enabled by an integrated output amplifier
• High-speed three-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP protocols
• Power-on reset circuit ensuring the output initializes to zero volts

Digital To Analog Converters Applications

• Battery-powered equipment requiring low power consumption
• Automotive sensor signal conditioning
• Motor control systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm if it denotes a specific tape-and-reel packaging variant or manufacturing lot code distinct from the standard 'NOPB' designation. Ensure the component meets AEC-Q100 qualification requirements for your target automotive application environment.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 12-bit resolution is required with rail-to-rail output swing. It is suitable for designs needing a wide supply voltage range (2.7 V to 5.5 V) and high-speed serial communication. Consider the SOT-23-THIN-6 package size constraints and the 1.8 MS/s update rate relative to system bandwidth needs.

Digital To Analog Converters Part Context

This part belongs to the DAC121S101 family of micro-power digital-to-analog converters. It serves as a direct replacement for legacy components such as the AD5320 and DAC7512. The family includes pin-compatible variants with different resolutions, such as the 8-bit DAC081S101 and the 10-bit DAC101S101, allowing for design flexibility within the same footprint.

Digital To Analog Converters Replacement Considerations

Publicly confirmed direct replacements include the DAC121S101 and DAC121S101-Q1. Other pin-compatible options within the series are the DAC081S101 and DAC101S101, though these offer lower resolution.
