ADC101S021CISDX/NOPB Equivalent & Substitute Parts

Part Overview

The ADC101S021CISDX/NOPB is a 10-bit Analog to Digital Converter manufactured by Texas Instruments, designed for single-ended input applications requiring SAR (Successive Approximation Register) architecture. This component operates across a wide supply voltage range of 2.7V to 5.25V for both analog and digital domains, with a sampling rate of 200 kSPS and SPI/DSP data interface compatibility. The device is housed in a 6-WSON (2.2x2.5mm) package with exposed pad and is currently in active production status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters.

Substitute Part Grouping Explanation

Substitute parts for the ADC101S021CISDX/NOPB are identified based on strict equivalence across the following critical parameters:

• Resolution: 10-bit conversion capability
• Sampling Rate: 200 kSPS performance
• Input Configuration: Single-ended input architecture
• Data Interface: SPI and DSP protocol support
• Supply Voltage Range: 2.7V to 5.25V for both analog and digital supplies
• Package Type: 6-WSON (2.2x2.5mm) with exposed pad
• Temperature Range: -40°C to 85°C operating specification
• Compliance: ROHS3 compliance and MSL Level 1 rating

The ADC101S021CISD/NOPB meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (ADC101S021) and differ only in packaging designation suffix, maintaining full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the ADC101S021CISDX/NOPB and ADC101S021CISD/NOPB are active production components from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on availability and supply chain requirements, as they are fully interchangeable in all applications requiring 10-bit SAR ADC functionality with single-ended input and SPI/DSP interface support.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The identical package footprint (6-WSON 2.2x2.5mm) and pinout enable direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)
