ADC081S101CISD

Analog To Digital Converters (ADC) Overview

The ADC081S101CISD is an obsolete 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input and operates with supply voltages ranging from 2.7V to 5.25V for both analog and digital domains. The device supports sampling rates up to 1 MSPS and utilizes SPI or DSP-compatible serial interfaces for data transfer. It is housed in a compact 6-WSON package measuring 2.2x2.5 mm, designed for surface-mount installation. The component functions as a sample-and-hold ADC with a 1:1 S/H to ADC ratio.

Analog To Digital Converters (ADC) Feature Summary

• Integrated sample-and-hold architecture for accurate signal capture
• Compact 6-pin WSON footprint suitable for space-constrained designs
• Compatible with standard SPI and DSP serial interface protocols

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems
• Industrial process control monitoring
• Data acquisition modules requiring low power consumption

Analog To Digital Converters (ADC) Procurement Notes

This specific part number is officially discontinued and no longer in production. Verification of availability should focus on the designated direct replacement, ADC081S101CISD/NOPB. Buyers must confirm RoHS compliance status differences between the original and lead-free variants before integration into new manufacturing processes.

Analog To Digital Converters (ADC) Selection Notes

Designers should evaluate the ADC081S101CISD/NOPB as the primary alternative due to identical functional specifications. Considerations include verifying package compatibility and ensuring that the lead-free construction meets environmental regulations. The replacement maintains the same pinout and electrical characteristics, facilitating direct substitution in existing layouts.

Analog To Digital Converters (ADC) Part Context

The ADC081S101 series represents Texas Instruments' entry-level SAR ADC family focused on cost-effective, low-power applications. This specific model provides 8-bit resolution at high speeds within a minimal footprint. The series is widely recognized for simplifying interface requirements through its flexible digital communication options.

Analog To Digital Converters (ADC) Replacement Considerations

ADC081S101CISD/NOPB serves as the direct functional substitute. Verify that the NOPB suffix indicates lead-free composition and updated packaging standards compared to the obsolete CISD variant.
