LT1674CS#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1674CS#PBF is a quad precision operational amplifier from Analog Devices, featuring ultralow power consumption with a maximum supply current of 2mA per amplifier. It offers rail-to-rail input and output capabilities, supporting a wide supply range from 2.2V to 36V. The device includes over-the-top inputs that operate above the positive supply voltage and provides reverse battery protection down to -18V. Key electrical specifications include a maximum input offset voltage of 375mV at 5V supply, a gain bandwidth product of 12kHz, and low input bias current of 250pA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-the-top inputs allow operation above the positive supply rail
• Reverse battery protection up to 18V for harsh environments
• Rail-to-rail input and output swing capability
• Ultralow power consumption suitable for battery systems

Instrumentation, Op Amps, Buffer Amps Applications

• Battery- or solar-powered systems
• Portable instrumentation
• Remote sensor amplifiers
• Photodiode amplifiers
• High impedance circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free (RoHS compliant) packaging when ordering. Confirm the package type matches the required PCB footprint, as this part number corresponds to the 14-lead SOIC variant. Ensure the operating temperature range requirements align with the commercial grade specifications provided in the datasheet before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high precision is required alongside minimal power usage. The decompensated design requires a minimum closed-loop gain of 5 for stability; unity gain applications require the LT1494 series instead. Consider the over-the-top feature if input signals may exceed the positive supply rail in single-supply configurations.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the LT1672/LT1673/LT1674 family of micropower op amps. The LT1674 specifically denotes the quad configuration housed in a 14-pin plastic small outline package. It shares core performance characteristics with the single (LT1672) and dual (LT1673) variants but integrates four independent amplifiers into one package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

For unity gain stable alternatives within the same family, consider the LT1494 series. Other related parts include the LT1636 for single-channel over-the-top applications.
