ADC12130CIWM

Analog To Digital Converters (ADC) Overview

The ADC12130CIWM is a discontinued 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 114 kS/s and supports single-ended, pseudo-differential, or differential input configurations via an integrated multiplexer and sample-and-hold circuit. The device functions on both analog and digital power supplies ranging from 3 V to 5.5 V. It utilizes an SPI-compatible serial interface for data communication. Key performance metrics include a maximum integral nonlinearity of +/- 2 LSB, a differential nonlinearity of +/- 1.5 LSB, and a gain error of 3 LSB. The component is housed in a 16-pin SOIC package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

This specific part number is obsolete and no longer in production. Verification of availability should focus on the direct replacement variant, ADC12130CIWMX/NOPB, which offers RoHS compliance. Sourcing must account for the discontinuation status and potential supply chain constraints associated with legacy components.

Analog To Digital Converters (ADC) Selection Notes

Designers should transition to the ADC12130CIWMX/NOPB to ensure long-term supply stability and regulatory compliance. The functional pinout remains identical, allowing for straightforward migration. Considerations must include verifying that the external reference voltage requirements align with the new variant's specifications.

Analog To Digital Converters (ADC) Part Context

The ADC12130 belongs to the ADC1213x family of 12-bit SAR converters. This series provides a balance between speed and precision for general-purpose data conversion tasks. The CIWM suffix indicates commercial temperature range and SOIC-16 packaging. The absence of the NOPB suffix denotes non-RoHS manufacturing, distinguishing it from current production units.

Analog To Digital Converters (ADC) Replacement Considerations

The verified direct substitute is ADC12130CIWMX/NOPB. This replacement maintains identical electrical characteristics and pin configuration while providing RoHS-compliant manufacturing. No hardware modifications are required for migration.
