LT1672CS8#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1672CS8#TRPBF is a single-channel, ultralow power operational amplifier from Analog Devices. It features over-the-top inputs that operate above the positive supply rail and reverse battery protection down to -18V. The device operates on a wide supply range of 2.2V to 36V with a maximum supply current of 2mA per amplifier. Key electrical specifications include a gain bandwidth product of 12kHz, an input offset voltage of up to 475mV, and an input bias current of 250pA. It provides rail-to-rail input and output capabilities in an 8-lead plastic SO package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'C' grade temperature range meets application requirements. Ensure the 8-lead SO package footprint matches the design layout. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high impedance inputs with minimal bias current errors. The over-the-top feature is critical for sensing signals exceeding the positive supply. Consider the decompensated nature (gain >= 5 stable) when configuring feedback networks. Evaluate the 12kHz bandwidth against signal frequency requirements before implementation.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1672/LT1673/LT1674 family of micropower precision op amps. While the LT1673 offers dual channels and the LT1674 provides quad channels, the LT1672 is configured as a single amplifier. All variants share identical electrical characteristics and pinouts within their respective package types.
