ADC122S625CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S625CIMMX/NOPB is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an adjustable sampling rate ranging from 50 kSPS to 200 kSPS and supports differential input configurations. The device utilizes a serial peripheral interface (SPI) for data communication and requires external reference voltage. It functions within a supply voltage range of 4.5 V to 5.5 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio of 73.2 dB, a signal-to-noise and distortion ratio of 72.5 dB, and a power consumption of 8.6 mW. The component is housed in a 10-lead MSOP package and is rated for operation between -40°C and +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Cross-reference the part number with official distributors to validate authenticity and current production status. Confirm that the external reference voltage source meets the required accuracy and noise specifications for the intended application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel resolution and moderate sampling speeds are required. Compare SNR and power dissipation against single-channel alternatives if channel count can be reduced. Evaluate the MSOP package dimensions against available PCB space constraints. Consider the need for external reference components and their impact on overall system cost and board area.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC122S625 family of dual-channel SAR ADCs. It shares architectural similarities with other members in the series but differs in channel count and specific performance parameters. The device complements single-channel variants like the ADC121S625 and higher-speed models within the broader data converter portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Direct parameter-equivalent substitutes may include other dual-channel 12-bit SAR ADCs from the same manufacturer family. Verify pinout compatibility and electrical specifications before substituting. Alternative packages such as WSON or QFN may require schematic and layout modifications.
