LT1783HS5#TRMPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1783HS5#TRMPBF is a single-channel operational amplifier housed in a 5-lead plastic TSOT-23 package. It operates on total supply voltages ranging from 2.5V to 18V with a maximum quiescent current of 300μA. Key electrical specifications include a gain bandwidth product of 1.25MHz, a slew rate of 0.42V/μs, and a maximum input offset voltage of 850μV at 25°C. The device features rail-to-rail input and output capabilities, reverse-battery protection up to 18V, and an operating temperature range of –40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-The-Top operation allows inputs to exceed the positive supply rail by up to 18V without phase reversal or damage.
• Reverse-battery protection enables safe operation with negative supply voltages up to 18V while drawing negligible current.
• Rail-to-rail input and output stages maintain signal integrity across the full supply voltage range.
• Phase reversal protection prevents false outputs when input voltages drop significantly below the negative supply.

Instrumentation, Op Amps, Buffer Amps Applications

• Portable instrumentation
• Battery- or solar-powered systems
• Sensor conditioning circuits
• Supply current sensing
• Battery monitoring

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix HS5 corresponds to the high-temperature industrial grade (-40°C to 125°C) and the 5-lead TSOT-23 package configuration. Confirm that the #TRMPBF designation indicates tape and reel packaging for automated assembly processes. Ensure compatibility with existing PCB footprints designed for the SOT-23 form factor before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when Over-The-Top input capability is required alongside low power consumption in a compact surface-mount package. It serves as a suitable alternative to the LT1782 when higher bandwidth and drive current are necessary. Consider the 6-lead version if system-level power management requires an integrated shutdown function to reduce standby currents.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1783 family of micropower, rail-to-rail operational amplifiers manufactured by Analog Devices. The series is characterized by its unique ability to handle input signals above the positive supply rail while maintaining low quiescent current draw. The HS5 variant specifically denotes the extended temperature grade and miniaturized packaging suitable for space-constrained portable electronics.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the LT1783 handle input voltages exceeding the positive supply rail?

The LT1783 features Over-The-Top operation, allowing inputs to go up to 18V above the negative supply regardless of the positive rail voltage, without causing phase reversal or output errors.

What is the behavior of the LT1783 during a reverse battery condition?

The device includes reverse-battery protection that limits supply current to less than 1nA when reverse voltages up to 18V are applied, protecting the circuit from damage.
