ADC101S101CISD/NOPB

Analog To Digital Converters (ADC) Overview

The ADC101S101CISD/NOPB is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates ranging from 500 ksps to 1 Msps and operates on a single supply voltage between 2.7 V and 5.25 V for both analog and digital domains. The device features an internal sample-and-hold amplifier and communicates via a standard SPI or DSP-compatible serial interface. It is housed in a compact 6-WSON package measuring 2.2 mm by 2.5 mm with exposed pad, designed for surface-mount installation across an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated sample-and-hold amplifier eliminates external buffering requirements
• Flexible serial interface compatible with standard SPI and DSP protocols
• Low-power architecture optimized for battery-operated applications

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems
• Industrial process control monitoring
• Battery-powered data acquisition devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and RoHS3 certification. Confirm the specific speed grade variant matches the design requirement, as performance specifications vary between 500 ksps and 1 Msps options within the same family. Check the package marking code against the datasheet to authenticate the manufacturer and date code upon receipt.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input channel with moderate resolution is required. Ensure the system clock frequency aligns with the desired sampling rate, as the device relies on an external clock input. Verify that the supply voltage remains within the specified 2.7 V to 5.25 V range to maintain signal integrity and conversion accuracy throughout the operating temperature range.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC101S101 family of micro-power ADCs from Texas Instruments. It shares architectural similarities with the ADC081S101 and ADC121S021 series, offering trade-offs between resolution, speed, and power consumption. The 10-bit resolution provides a balance between precision and bandwidth for general-purpose data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

ADC101S101CISD/NOPB serves as the non-rohs predecessor. For direct pin-compatible substitution, verify the speed grade match with ADC101S101CIMD/NOPB or ADC101S021 variants if lower throughput is acceptable.
