ADC101S021CIMF/NOPB

Analog To Digital Converters (ADC) Overview

The ADC101S021CIMF/NOPB is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. Originally developed under the National Semiconductor brand, this device operates with a sampling rate of 200 kSPS and supports supply voltages between 2.7 V and 5.25 V for both analog and digital domains. It features a single-ended input configuration and communicates via an SPI-compatible serial interface. The component is housed in a 10-MSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 200 kSPS sampling rate
• Single-ended input with internal sample-and-hold
• SPI/DSP compatible serial interface
• Wide supply voltage range: 2.7V to 5.25V

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation
• Industrial process control systems
• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify that the manufacturer designation is Texas Instruments, as National Semiconductor was acquired. Confirm the suffix /NOPB indicates lead-free/RoHS compliance. Ensure the MSOP-10 package matches the design requirements. Check for availability from authorized distributors as original National Semiconductor stock is discontinued.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-pin-count, single-channel ADC is required for moderate-speed applications. Compare against the ADC101S021CISDX variant if a smaller WSON package is preferred over the MSOP form factor. Verify that the 200 kSPS speed meets the system bandwidth needs and that the single-ended input architecture suits the signal source.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC101S021 family of low-power, 10-bit SAR ADCs. While originally branded under National Semiconductor, current production and datasheets are managed by Texas Instruments following their acquisition. The /NOPB suffix denotes a lead-free finish compliant with RoHS standards, distinguishing it from older non-compliant variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC101S021CISDX/NOPB is a parameter-equivalent alternative available in a 6-WSON package. Designers must verify pin compatibility or adjust PCB layout when substituting between the MSOP and WSON packages.
