ADC101S021CIMFX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC101S021CIMFX/NOPB is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates from 40 kSPS to 200 kSPS and operates with supply voltages between 2.7 V and 5.5 V for both analog and digital domains. The device utilizes a serial interface compatible with SPI, QSPI, and Microwire standards. Packaged in an 8-pin SOT-23 format, it is designed for low-power applications requiring moderate resolution and speed.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required PCB footprint for the 8-pin SOT-23 configuration before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single channel with 10-bit resolution is sufficient. Compare against higher-resolution models like the ADC124S101 if greater precision is needed. Consider the 200 kSPS maximum speed limit for high-frequency signal acquisition requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC101S021 family of low-power, single-channel ADCs. It serves as a cost-effective solution for applications where power consumption and pin count are critical constraints compared to multi-channel or higher-speed alternatives.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same series include the ADC101S021CIMM/NOPB in an MSOP-10 package. Verify pin compatibility and thermal characteristics when substituting packages.
