ADC128S052QCMTX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC128S052QCMTX/NOPB is an automotive-grade, eight-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate ranging from 200 kSPS to 500 kSPS and accepts single-ended inputs on channels IN0 through IN7. The device supports independent analog (VA) and digital (VD) power supplies, both operating within a voltage range of 2.7 V to 5.25 V. It features a serial interface compatible with SPI, QSPI, and MICROWIRE standards. The component is housed in a 16-pin TSSOP package and is qualified for AEC-Q100 Grade 1 certification, ensuring reliability in harsh environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix QCMTX/NOPB against the manufacturer's current datasheet to confirm the exact temperature grade and packaging configuration. Ensure that the ordering documentation matches the intended automotive qualification requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components during the sourcing process.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an eight-channel, 12-bit resolution is required for automotive-grade applications. It is suitable for designs needing high-speed conversion up to 500 kSPS with low power consumption. Consider the TSSOP-16 package constraints and the requirement for separate analog and digital ground planes to minimize noise coupling in sensitive measurement circuits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC128S052 family, which includes industrial variants like the ADC128S052CIMTX/NOPB. The 'Q' designation indicates automotive qualification under AEC-Q100 standards.
