ADC128S102CIMTX

Analog To Digital Converters (ADC) Overview

The ADC128S102CIMTX is a discontinued 12-bit successive approximation register (SAR) analog-to-digital converter featuring eight single-ended inputs. It supports sampling rates from 50 kSPS to 1 MSPS and utilizes a TSSOP-16 package. The device operates on dual power supplies, with both analog (VA) and digital (VD) voltages ranging from 2.7V to 5.25V. It employs an SPI-compatible serial interface for data transfer and configuration. The component includes an internal track-and-hold circuit and functions within a temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel multiplexed input architecture with integrated track-and-hold circuitry
• High-speed conversion capability up to 1 MSPS with 12-bit resolution
• Flexible serial communication supporting standard SPI, QSPI, and Microwire protocols
• Dual independent power supply domains for analog and digital sections

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for environmental monitoring
• Battery-powered instrumentation utilizing low-power operational modes
• Automotive sensor interfaces operating in extended temperature ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify the obsolete status of this specific suffix variant before procurement planning. The non-NOPB designation indicates lead-based construction which may not comply with current RoHS directives. Confirm availability of the NOPB-compliant replacement through authorized distributors. Ensure supply chain strategies account for potential long-lead times or limited stock levels associated with end-of-life components.

Analog To Digital Converters (ADC) Selection Notes

Select the NOPB version for projects requiring lead-free compliance and modern manufacturing standards. Evaluate the ADC128S022 if lower sampling speeds suffice, as it offers cost advantages for slower applications. Consider the ADC128S052 for intermediate speed requirements between 200 kSPS and 500 kSPS. Verify that the 12-bit resolution meets system accuracy needs without unnecessary overhead compared to higher-resolution alternatives.

Analog To Digital Converters (ADC) Part Context

This component belongs to the Texas Instruments ADC128S family of high-speed, multi-channel SAR ADCs. It serves as a bridge between analog sensor signals and digital processing units in embedded systems. The device was widely used in applications demanding moderate speed and multiple input channels. Its discontinuation reflects the transition toward lead-free manufacturing processes across the semiconductor industry.

Analog To Digital Converters (ADC) Replacement Considerations

The direct functional substitute is the ADC128S102CIMTX/NOPB, which maintains identical electrical specifications while adhering to RoHS standards. Designers should verify pin compatibility and software register configurations remain unchanged during migration.
