ADC101S021CISDX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC101S021CISDX/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 200k samples per second. The device features a single-ended input configuration and utilizes a sample-and-hold architecture with a 1:1 ratio. Data transfer is facilitated through SPI and DSP-compatible serial interfaces. It is housed in a compact 6-WSON package measuring 2.2x2.5 mm with an exposed pad, designed for surface-mount installation. The component functions reliably within an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 10-bit SAR ADC core with a built-in sample-and-hold circuit for accurate signal acquisition.
• Supports standard SPI and DSP serial interface protocols for straightforward digital communication.
• Operates on a single power supply ranging from 2.7V to 5.25V for both analog and digital domains.
• Utilizes a small 6-WSON footprint to minimize board space requirements.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems
• Industrial process control data acquisition
• Consumer electronics requiring low-power analog digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CISDX' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering quantity aligns with the tape and reel packaging standards provided by the supplier. Cross-reference the RoHS3 compliance status with current regulatory requirements for the target market before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended, 10-bit resolution is sufficient for the application. Consider the 200ksps sampling rate limit for bandwidth requirements. Evaluate the 6-WSON package constraints for thermal management and PCB layout. Compare against higher-resolution or multi-channel alternatives if system complexity increases.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC101S021 family of micro-power ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific 10-bit resolution and 200ksps speed. The 'NOPB' suffix indicates lead-free construction without phosphorus bromide, adhering to environmental standards.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC101S021CISD/NOPB is documented as a parameter-equivalent substitute. Verify pin compatibility and ensure the non-suffix variant meets all electrical requirements before substitution.
