ADC104S021CIMM

Analog To Digital Converters (ADC) Overview

The ADC104S021CIMM is a quad-channel, 10-bit analog-to-digital converter manufactured by National Semiconductor. It utilizes a successive approximation register (SAR) architecture to achieve sampling rates up to 500 kSPS per channel. The device features a serial interface compatible with standard SPI protocols and operates on a single 2.7 V to 5.25 V supply for both analog and digital domains. Packaged in a 10-lead MSOP format, it integrates an internal track-and-hold circuit for each input channel, ensuring accurate signal acquisition across all four differential or single-ended inputs.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel configuration with independent track-and-hold circuits
• 10-bit resolution with 500 kSPS sampling rate per channel
• Single-supply operation from 2.7 V to 5.25 V
• SPI-compatible serial interface

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin as National Semiconductor, noting that Texas Instruments acquired the semiconductor business. Confirm the specific suffix 'CIMM' corresponds to the commercial temperature range and MSOP-10 package. Ensure compatibility with existing PCB footprints for the 10-lead mini-small-outline package before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a multi-channel solution is required without external multiplexers. The integrated track-and-hold on each channel simplifies board layout compared to single-channel ADCs requiring external switches. Verify that the 10-bit resolution meets system accuracy requirements and that the 500 kSPS speed aligns with the application bandwidth needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC104S family of high-speed, low-power ADCs. It serves as a multi-channel alternative to single-channel devices like the ADC104S021, reducing component count in designs requiring multiple simultaneous conversions. The CIMM variant specifically denotes the commercial grade operating temperature range within the MSOP package style.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC104S021Q may be considered if automotive qualification is not required but pin compatibility is needed. Cross-reference with TI datasheets for updated electrical specifications following the National Semiconductor acquisition.
