ADC12130CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12130CIWM/NOPB is a self-calibrating, single-channel 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a Successive Approximation Register (SAR) architecture and operates with supply voltages ranging from 3 V to 5.5 V for both analog and digital domains. The device supports a maximum sampling rate of 114 kS/s and features an SPI-compatible serial interface. It accommodates differential, pseudo-differential, or single-ended input configurations within a 16-pin SOIC package. Key performance metrics include a differential nonlinearity (DNL) of ±1.5 LSB, integral nonlinearity (INL) of ±2 LSB, and a gain error of 3 LSB. Power consumption is specified at 22.5 mW, with an operating temperature range extending from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated self-calibration mechanism reduces system-level calibration requirements.
• Flexible input configuration supporting differential, pseudo-differential, and single-ended modes.
• Low power consumption suitable for battery-operated applications.
• External reference voltage capability allows optimization for specific signal ranges.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power and moderate resolution.
• Industrial process control data acquisition modules.
• Medical equipment involving physiological signal monitoring.
• Battery-powered sensor interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as discontinued or obsolete through official Texas Instruments channels before finalizing design-in decisions. Confirm that the NOPB suffix indicates lead-free and RoHS compliance relative to current environmental regulations. Ensure the SOIC-16 package dimensions match the target PCB footprint constraints. Cross-reference the specific revision level if long-term availability is critical for production runs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel 12-bit resolution is sufficient for the application's accuracy needs. The SAR architecture offers a balance between speed and power efficiency compared to sigma-delta alternatives. Consider the external reference requirement if high precision is necessary, as internal references are not present. Evaluate the 114 kS/s sampling rate against the Nyquist criteria for the highest frequency component in the input signal.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12130 series, which includes variants like the ADC12130CIWMX. The NOPB designation signifies a lead-free, RoHS-compliant version of the original CIWMX part. It serves as a direct replacement for the older non-RoHS compliant versions while maintaining identical electrical characteristics and pinout compatibility within the same family.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12130CIWMX/NOPB is listed as a direct replacement for the discontinued ADC12130CIWMX. Verify pinout compatibility and electrical specifications when substituting other 12-bit SAR ADCs from different manufacturers.
