LTC2065IF#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2065IF#TRPBF is a quad, low-power, zero-drift operational amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 5.25V and features a typical supply current of 1.4µA per amplifier with a maximum of 2µA. The device provides rail-to-rail input and output capabilities, an open-loop gain of 140dB typical, and a gain-bandwidth product of 20kHz. Input offset voltage is specified at a maximum of 5µV with a drift of 0.02µV/°C over the industrial temperature range of –40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the 'I' grade designation aligns with the necessary –40°C to 85°C operating temperature range for your specific application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad configuration is required alongside extremely low quiescent current and high precision. Ensure the design accommodates the 20kHz bandwidth limit and utilizes the shutdown pin to manage power budgets effectively in battery-operated or energy-harvesting scenarios.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2063/LTC2064/LTC2065 family of zero-drift amplifiers. While the LTC2063 is single-channel and the LTC2064 is dual-channel, the LTC2065 integrates four amplifiers into a single package. All variants share identical electrical characteristics regarding offset, bias current, and noise performance.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the internal chopping frequency affect signal integrity?

The internal chopping frequency is 5kHz. Advanced circuit techniques suppress spurious idle tones associated with self-calibration, allowing for trouble-free use without significant artifacts in the signal band.

What is the behavior of the SHDN pin?

Tying the SHDN pin to V+ enables the device. Tying it to V– disables the amplifier, reducing supply current to less than 170nA per amplifier. Floating this pin is not recommended.
