LT1672IS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1672IS8#PBF is a dual precision operational amplifier from Analog Devices, featuring ultralow supply current of 2µA maximum per amplifier. It offers rail-to-rail input and output capabilities with an over-the-top input range extending above the positive supply rail up to 36V. The device provides low offset voltage (375mV max), high open-loop gain (100V/mV min), and reverse battery protection down to -18V. Designed for stability at gains of 5 or higher, it operates on supply voltages ranging from 2.2V to 36V.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-the-top inputs operate above the positive supply rail
• Ultralow power consumption with 2µA maximum supply current
• Reverse battery protection up to 18V
• Rail-to-rail input and output swing

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 package type matches the required PCB footprint, as the IS8 suffix indicates an 8-lead plastic SOIC package. Confirm that the application circuit maintains a closed-loop gain of at least 5 to ensure stability, as this is a decompensated op amp. Ensure supply voltages remain within the specified 2.2V to 36V range during operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low power consumption is critical alongside precision requirements. It is suitable for applications requiring inputs to exceed the positive supply rail. Note that unity gain stable versions are available in the LT1494/LT1495/LT1496 series if lower gain configurations are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1672/LT1673/LT1674 family of micropower precision op amps. The LT1672 specifically denotes the dual-channel configuration. These devices are designed for harsh environments due to their robust input protection and wide supply range, making them distinct from standard precision amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LT1494/LT1495/LT1496 are unity gain stable versions of this family.
