ADC122S101CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S101CIMMX/NOPB is a low-power, two-channel CMOS 12-bit analog-to-digital converter manufactured by Texas Instruments. It features a successive-approximation register architecture with an internal track-and-hold circuit and operates over a sample rate range of 500 ksps to 1 Msps. The device accepts single-ended inputs from IN1 and IN2, ranging from 0V to the analog supply voltage (VA). It utilizes a high-speed serial interface compatible with SPI, QSPI, and MICROWIRE standards. Powered by a single supply between 2.7V and 5.25V, it delivers typical power consumption of 4.3 mW at 3V and 13.1 mW at 5V during normal operation.

Analog To Digital Converters (ADC) Feature Summary

• Dual input channels (IN1, IN2) with configurable multiplexing via control register
• Fully specified performance across 500 ksps to 1 Msps sample rates
• Typical Signal-to-Noise Ratio (SNR) of 72.4 dB and Integral Non-Linearity (INL) of ±0.64 LSB
• Variable power management with shutdown current as low as 0.14 µW

Analog To Digital Converters (ADC) Applications

• Portable battery-powered systems requiring low power consumption
• Remote data acquisition networks
• Instrumentation and industrial control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific package type and temperature rating required for the design. Confirm that the ordering suffix corresponds to the intended manufacturing revision and packaging format. Ensure compatibility with existing supply chain sources before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is needed within the 500 ksps to 1 Msps throughput range. It is suitable for designs requiring a single-supply operation between 2.7V and 5.25V. Consider pin-compatible alternatives like the ADC122S051 if lower sampling rates are sufficient for the application requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC122 series of 12-bit successive-approximation ADCs. It shares pinout and functional compatibility with other members of the family, such as the ADC122S021 and ADC122S051, which offer different speed grades. The CIMMX/NOPB designation indicates a specific tape-and-reel packaging configuration without lead-based halogens.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include the ADC122S051 (200–500 ksps) and ADC122S021 (50–200 ksps). These devices maintain identical pinouts and control logic but operate at lower maximum sample rates.
