ADC128S052QCMT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC128S052QCMT/NOPB is an automotive-grade, 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates from 200 kSPS to 500 kSPS with a single-ended input architecture. The device operates on a supply voltage range of 2.7 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB, integral nonlinearity (INL) of +/- 1 LSB, and differential nonlinearity (DNL) of -0.9 LSB to 1.3 LSB. It features a SPI-compatible serial interface and is housed in a TSSOP-16 package, rated for operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'Q' suffix indicates automotive grade qualification when sourcing. Confirm the specific tape-and-reel packaging format matches your assembly line requirements. Ensure the component date code aligns with your manufacturing timeline. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit risks. Validate RoHS compliance status for environmental regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended channels are required within a compact TSSOP-16 footprint. It is appropriate for designs needing 12-bit resolution at speeds up to 500 kSPS. Consider this part for automotive environments requiring extended temperature ranges. Compare against the standard commercial version if automotive certification is not mandatory.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC128S052 family, which provides multi-channel conversion capabilities. The QCMT variant specifically denotes the automotive quality tier and tape-and-reel packaging. It shares architectural similarities with other SAR ADCs but is optimized for cost-effective, high-channel-count applications in constrained spaces.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC128S052CIMT/NOPB serves as the commercial-grade equivalent with identical electrical specifications but without automotive qualification. Verify pin compatibility and software register settings before substitution.
