LT1672IN8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1672IN8#PBF is a single-channel precision operational amplifier from the LT1672/LT1673/LT1674 family, manufactured by Analog Devices Inc. It features ultralow supply current of 2mA maximum per amplifier and operates with a wide supply range from 2.2V to 36V. The device offers rail-to-rail input and output capabilities, with inputs that can operate above the positive supply voltage (Over-The-Top). Key electrical specifications include a maximum input offset voltage of 375mV at VS=5V, a gain bandwidth product of 12kHz, and reverse battery protection down to -18V. It is designed for high impedance circuits and low power applications.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-The-Top input capability allowing operation above the positive supply rail
• Rail-to-rail input and output swing for maximum dynamic range
• Reverse battery protection up to -18V for harsh environment reliability

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered systems
• Portable instrumentation
• Remote sensor amplifiers
• Micropower filters
• Photodiode amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IN8 corresponds to the 8-lead PDIP package variant when sourcing. Confirm the temperature grade matches design requirements, as the 'I' suffix denotes guaranteed performance over the extended industrial range of -40°C to 85°C. Ensure compatibility with existing PCB footprints for the N8 package style before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring extreme low power alongside precision DC accuracy. It is suitable where input signals may exceed the positive supply rail or where reverse polarity protection is needed without external components. Consider the decompensated nature (gain stable at AV >= 5) when configuring feedback networks to ensure stability.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1672/LT1673/LT1674 series of micropower op amps. While the LT1672 is the single-channel version, the family includes dual (LT1673) and quad (LT1674) variants sharing identical electrical characteristics. These devices are positioned as alternatives to unity-gain stable versions like the LT1494 series, offering higher open-loop gain at the cost of minimum closed-loop gain stability.
