ADC101S021CISD/NOPB

Analog To Digital Converters (ADC) Overview

The ADC101S021CISD/NOPB is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog and digital supply voltage range of 2.7V to 5.25V and supports a maximum sampling rate of 200ksps. The device features a single-ended input configuration and communicates via SPI or DSP-compatible serial interfaces. Packaged in a compact 6-WSON (2.2x2.5mm) surface-mount footprint with exposed pad, it is designed for space-constrained applications. The component functions within an industrial temperature range of -40°C to +85°C and complies with RoHS3 standards.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a sample-and-hold amplifier with the ADC core for accurate signal capture
• Supports standard SPI and DSP serial interface protocols for flexible microcontroller connectivity
• Operates on a single low-voltage power supply ranging from 2.7V to 5.25V

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems
• Industrial process control data acquisition
• Consumer electronics requiring high-resolution sensing

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging options. Confirm that the required package variant matches the design layout, as the base model may be available in different tape-and-reel or cut-tape configurations depending on distributor inventory. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input architecture is sufficient for the application, as opposed to differential variants like the ADC124S101. Ensure the system requires a 10-bit resolution and up to 200ksps throughput, which balances performance and power consumption effectively. Verify that the host processor supports the required SPI clock speeds and timing constraints defined in the electrical characteristics section of the official documentation.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC101S021 family of low-power, single-channel SAR ADCs. It shares architectural similarities with other members such as the ADC101S021CISDX/NOPB, differing primarily in packaging or reel specifications. The series is designed to provide cost-effective solutions for general-purpose data conversion tasks where moderate speed and resolution are required without complex multiplexing needs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC101S021CISDX/NOPB is documented as a parameter-equivalent substitute. Verify pin compatibility and thermal performance before swapping between the ISD and ISDX suffixes.
