ADC122S051QIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S051QIMMX/NOPB is a dual-channel, 12-bit CMOS analog-to-digital converter manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with an internal track-and-hold circuit. The device supports a sampling rate range of 200 ksps to 500 ksps and operates on a single supply voltage from 2.7 V to 5.25 V. It offers a typical signal-to-noise ratio (SNR) of 72.5 dB and consumes approximately 3.0 mW at 3 V or 10 mW at 5 V. The component is housed in an 8-pin VSSOP package and is qualified under AEC-Q100 standards for automotive applications.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel input capability allowing simultaneous acquisition of two analog signals
• Wide sampling rate specification across the 200 ksps to 500 ksps range
• Automotive qualification compliant with AEC-Q100 standards
• Low power consumption with dedicated shutdown mode functionality

Analog To Digital Converters (ADC) Applications

• Automotive electronic systems requiring reliable data conversion
• Portable battery-powered equipment due to low power operation
• Remote data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IMMX' against official Texas Instruments documentation to confirm package variant and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 reliability standards for the intended automotive application environment. Cross-reference the datasheet revision date to validate parameter accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel SAR ADC with automotive qualification is required. It is suitable for designs needing flexible sampling rates between 200 ksps and 500 ksps. Consider the 8-pin VSSOP footprint for space-constrained PCB layouts. Verify that the 2.7 V to 5.25 V supply range aligns with the system power architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC122S051 family of high-performance 12-bit analog-to-digital converters. The 'Q' designation indicates automotive qualification, while 'NOPB' signifies lead-free packaging without halogenated flame retardants. The device integrates a serial interface compatible with standard DSP protocols.

Analog To Digital Converters (ADC) Replacement Considerations

The non-automotive grade ADC122S051CIMM/NOPB serves as a functional substitute if automotive qualification is not required. Both parts share identical electrical specifications and pinouts.
