LT1782HS5#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1782HS5#TRPBF is a micropower operational amplifier in a 5-lead SOT-23 package. It features Over-The-Top operation, allowing inputs to exceed the positive rail by up to 18V. The device operates on single or split supplies from 2.5V to 18V with a maximum quiescent current of 55µA. Key electrical parameters include a gain bandwidth product of 200kHz, a slew rate of 0.07V/µs, and an input offset voltage of 950µV max at extended temperatures. It provides reverse battery protection up to 18V and supports output currents up to 18mA while maintaining rail-to-rail performance.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-The-Top capability allows input voltages to exceed the positive supply rail without phase reversal
• Reverse battery protection handles negative supply voltages up to 18V with negligible current draw
• Rail-to-rail input and output stages maintain signal integrity across the full supply range
• Micropower consumption ensures low energy usage suitable for battery-operated systems

Instrumentation, Op Amps, Buffer Amps Applications

• Portable instrumentation
• Battery monitoring circuits
• Sensor conditioning
• 4mA to 20mA transmitters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific temperature grade suffix 'H' corresponds to the required -40°C to 125°C operating range for your design. Confirm the 5-lead SOT-23 package matches your PCB footprint requirements. Ensure the datasheet specifications for the HS5 variant are reviewed against system voltage and load constraints before finalizing the bill of materials.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common-mode voltage tolerance above the supply rail is necessary. The 5-lead package lacks a shutdown pin; designs requiring power-down functionality must use the 6-lead version. Verify that the 200kHz bandwidth meets the signal frequency requirements and that the 55µA supply current fits the power budget constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1782 family of micropower op amps. The 'HS5' designation indicates the industrial/high-temperature grade (LT1782H) packaged in the 5-lead ThinSOT format. It shares core architecture with the LT1783 but offers lower bandwidth. The '#TRPBF' suffix denotes tape and reel packaging with lead-free finish.
