NCS20231SQ3T2G

Instrumentation, Op Amps, Buffer Amps Overview

The NCS20231SQ3T2G is a single-channel operational amplifier from onsemi, housed in an SC-88 (SC-70-5) surface-mount package. It operates within a supply voltage range of 2.7 V to 36 V and supports an industrial temperature range of -40 °C to 125 °C. Key electrical specifications include a unity-gain bandwidth of 3 MHz, a maximum input offset voltage of ±1.2 mV across the full temperature range, and a quiescent current of approximately 0.595 mA at 25 °C. The device features rail-to-rail output capability and high common-mode rejection ratios.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output performance with functional input common-mode voltage extending beyond supply rails
• Wide operating supply voltage range supporting applications from low-voltage to high-voltage systems
• High common-mode rejection ratio ensuring accurate signal processing under varying conditions
• Robust input protection structure allowing safe operation with differential voltages up to the supply limit

Instrumentation, Op Amps, Buffer Amps Applications

• Telecom equipment signal conditioning
• Power supply design feedback loops
• Diesel injection control systems
• Automotive sensor interfaces

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix SQ3T2G corresponds to the SC-88 package and standard industrial temperature grade (-40 °C to 125 °C). Confirm that the component lacks the NCV prefix, indicating it is not automotive qualified under AEC-Q100 standards. Ensure compatibility with required tape and reel shipping quantities specified by the manufacturer for this package style.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a wide supply voltage range up to 36 V is required alongside moderate speed performance. It is suitable for designs needing rail-to-rail output swing without phase reversal issues. Consider alternative packages like TSOP-5 or SOT-553 if footprint constraints differ. Choose the NCV20231 variant if automotive qualification and extended temperature ratings are necessary for the application environment.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NCS2023x series of operational amplifiers designed for general-purpose analog signal processing. The series includes single, dual, and quad channel variants, though this specific part number denotes the single-channel configuration. The family is characterized by its ability to operate efficiently across a broad voltage spectrum while maintaining stability with capacitive loads.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same series include NCS20231SN2T1G (TSOP-5 package) and NCS20231XV53T2G (SOT-553 package). For automotive-grade requirements, the NCV20231SQ3T2G offers identical electrical characteristics but with extended temperature ranges and AEC-Q100 qualification.
