LT1013IS8

Instrumentation, Op Amps, Buffer Amps Overview

The LT1013IS8 is a dual precision operational amplifier manufactured by Analog Devices Inc. It features two channels with a guaranteed maximum input offset voltage of 150µV and a maximum drift of 2µV/°C. The device operates on a single 5V supply or dual supplies up to ±22V, drawing a maximum supply current of 500µA per amplifier. It provides high gain (minimum 0.8 million at 17mA load) and low noise (0.55µVP-P from 0.1Hz to 10Hz). The output swings to ground while sinking current, and the input common mode range extends to ground.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IS8 corresponds to the industrial temperature grade (-40°C to 85°C) and SO-8 package configuration. Confirm lead-free finish status (#PBF) if required for assembly processes. Check for obsolete package warnings in official documentation and identify recommended alternate source packages such as N or S8 variants if availability is constrained.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when upgrading designs requiring pin compatibility with legacy MC1458 or LM324 devices but demanding higher precision. It is suitable for applications needing rail-to-rail input/output characteristics near the negative supply without phase reversal issues. Consider the low supply current for battery-operated systems and the guaranteed offset specifications for high-accuracy signal conditioning tasks.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1013 is part of the LT1013/LT1014 family of precision operational amplifiers. It serves as the dual-channel counterpart to the quad LT1014. Designed to directly replace older precision op amps like the MC1458 and OP-221, it offers superior performance in an industry-standard 8-pin configuration. The series is known for its ability to operate effectively on single 5V supplies while maintaining high gain and low noise characteristics.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LT1013 exhibit output phase reversal when inputs go below ground?

No, the LT1013 includes unique phase reversal protection circuitry that prevents output phase reversal even when inputs are driven significantly below the negative supply rail.

What is the minimum supply voltage for proper operation?

The minimum supply voltage for proper operation is 3.4V, which corresponds to three Ni-Cad batteries.
