LT1806IS8

Instrumentation, Op Amps, Buffer Amps Overview

The LT1806IS8#PBF is a single-channel, low noise, rail-to-rail input and output unity-gain stable operational amplifier. It features a gain-bandwidth product of 325MHz, a slew rate of 140V/μs, and an output current capability of 85mA. The device operates within a supply voltage range of 2.5V to 12.6V. Key electrical specifications include a maximum input offset voltage of 700μV, a common mode rejection ratio of 106dB typical, and a power supply rejection ratio of 105dB typical. It is housed in an 8-lead plastic SO package and is specified for operation over the industrial temperature range of –40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capabilities maximize signal dynamic range in low supply applications.
• Low distortion and low noise characteristics support high performance data acquisition systems.
• Inputs can be driven beyond the supply rails without damage or phase reversal.
• Integrated shutdown pin allows for significant power reduction when disabled.

Instrumentation, Op Amps, Buffer Amps Applications

• Low voltage, high frequency signal processing
• Driving A/D converters
• Rail-to-rail buffer amplifiers
• Active filters
• Video line drivers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to 85°C) and the 8-lead SOIC package. Ensure the datasheet version matches the required electrical characteristics for your design constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high speed and precision with single-supply operation. The rail-to-rail I/O eliminates the need for dual supplies in many low-voltage applications. Consider the 85mA output current for driving moderate loads directly. Verify that the 325MHz bandwidth meets the system's frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1806/LT1807 family of precision op amps from Analog Devices (formerly Linear Technology). The LT1806 is the single-channel variant, while the LT1807 is the dual-channel version. Both share similar electrical characteristics but differ in channel count and package options.

Instrumentation, Op Amps, Buffer Amps FAQ

Can the inputs be driven beyond the supply rails?

Yes, the inputs can be driven beyond the supplies without damage or phase reversal of the output.

What is the purpose of the SHDN pin?

The SHDN pin allows the device to be put into a low-power shutdown state, reducing supply current significantly.
