ADC104S021QIMM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC104S021QIMM/NOPB is a quad-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates up to 200 kSPS and operates with supply voltages ranging from 2.7 V to 5.25 V for both analog and digital domains. The device features a serial peripheral interface (SPI) compatible with standard modes. Packaged in an 8-pin VSSOP format, it is designed for automotive applications, meeting AEC-Q100 qualification standards. Key performance metrics include a signal-to-noise ratio of approximately 60 dB and low power consumption suitable for battery-operated systems.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture enables simultaneous acquisition across four independent analog inputs within a single compact package.
• Automotive-grade reliability ensures compliance with AEC-Q100 standards for harsh operating environments.
• Low-power SAR design optimizes energy efficiency for portable and battery-supplied instrumentation applications.

Analog To Digital Converters (ADC) Applications

• Automotive sensor interfaces for temperature, pressure, and position monitoring
• Industrial data acquisition systems requiring multi-channel input
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the 'Q' designation aligns with required automotive qualification standards for your specific application environment. Ensure the VSSOP-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four channels are required without increasing board space. Compare against single-channel alternatives if channel count is flexible. Verify that the 10-bit resolution meets system accuracy needs, as higher precision models exist in the same family. Ensure SPI timing constraints match the host microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC10xS021 family of low-power, 10-bit SAR ADCs. It shares architectural similarities with the ADC12xS021 series but offers reduced resolution. The QIMM variant specifically targets automotive markets, distinguishing it from commercial grade counterparts through extended temperature ranges and rigorous testing protocols defined by Texas Instruments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes include other members of the ADC10xS021 family such as the ADC104S021CIMM/NOPB for commercial use. For higher resolution, the ADC124S021 series may be considered if software adaptation is feasible. Verify thermal and electrical specifications match before swapping.
