LT1413S8

Instrumentation, Op Amps, Buffer Amps Overview

The LT1413S8 is a dual precision operational amplifier manufactured by Analog Devices Inc., housed in an 8-lead plastic SOIC package. Designed for single-supply operation, it features a maximum input offset voltage of 380μV and a supply current of 480μA per amplifier at 5V. The device offers a gain-bandwidth product of 950kHz and includes phase reversal protection. It operates within a temperature range of –40°C to 85°C, providing high channel separation and low noise characteristics suitable for precision analog signal processing applications.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix and package type against official manufacturer documentation before procurement. Ensure compatibility with required operating temperature ranges and electrical specifications. Confirm that the component meets all necessary industry standards and regulatory requirements for the intended application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the LT1413S8 when single-supply precision is required with inputs capable of going below ground. Consider its low cost and robust phase reversal protection compared to older generations. Evaluate supply current constraints as it draws more power than micropower alternatives but offers higher speed than those devices.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1413 serves as a low-cost upgrade to the industry-standard LT1013 dual single-supply op amp. It is optimized specifically for single 5V applications while maintaining specifications for ±15V operation. The S8 variant denotes the 8-lead plastic SOIC package configuration, differing from the DIP pin locations to follow standard SO package layouts.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the LT1413 handle input voltages below ground?

The LT1413 allows the input to go below ground, up to 5V below the negative supply, due to internal 400Ω series resistors that protect the device from substrate current flow.

What is the purpose of the phase reversal protection?

The unique phase reversal protection circuitry ensures the output does not reverse polarity when inputs exceed the common-mode range, preventing servo system lock-up.
