LT1014ISW#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1014ISW#TRPBF is a quad precision operational amplifier manufactured by Analog Devices Inc. It features four independent amplifiers in a 16-lead plastic SO package with an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum input offset voltage of 150µV, a gain-bandwidth product of 800 kHz, and a slew rate of 400 mV/µs. The device operates on supply voltages ranging from 4 V to 44 V, drawing a typical supply current of 350 µA per amplifier. It provides high common-mode rejection of 117 dB and low input bias current of 12 nA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for automated assembly. Confirm the ISW designation corresponds to the 16-lead SOIC package and the I grade ensures the -40°C to +85°C operating temperature range. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct lot traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when upgrading existing designs based on LM324 or LM348 architectures without compromising board space. It is suitable for applications requiring high DC accuracy, such as low offset voltage and drift, alongside single-supply compatibility. Ensure the required channel count matches the quad configuration and that the 16-lead SO package fits the PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LT1013/LT1014 family of precision operational amplifiers. The LT1014 specifically provides a quad configuration, whereas the LT1013 offers a dual configuration. Both are designed to replace older general-purpose amplifiers like the MC1458 or OP-221 with significantly improved precision metrics including lower noise and higher gain.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LT1014 exhibit output phase reversal if the input voltage goes below ground?

No, the LT1014 includes unique phase reversal protection circuitry that prevents the output from reversing 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 allows for battery-powered applications using three Ni-Cad cells.
