LTC2065HUD#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2065HUD#TRPBF is a quad, low-power, zero-drift operational amplifier manufactured by Analog Devices. It features a typical supply current of 1.4µA per amplifier with a maximum of 2µA. The device provides an input offset voltage of 5µV maximum and an offset drift of 0.05µV/°C over the extended temperature range. Input bias current is limited to 100pA maximum across the full operating temperature range. It operates on a supply voltage from 1.7V to 5.25V and includes a shutdown mode drawing less than 500nA. The component is housed in a 16-lead (3mm × 3mm) plastic QFN package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Self-calibrating circuitry ensures ultra-low input offset voltage and minimal drift over temperature variations.
• Integrated EMI filter provides high rejection against radio frequency interference at common frequencies.
• Shutdown control pin allows for significant power reduction in duty-cycled applications with low charge loss during power-up.
• Rail-to-rail input and output capability supports operation within the entire supply voltage range.

Instrumentation, Op Amps, Buffer Amps Applications

• Signal conditioning in wireless mesh networks
• Portable instrumentation systems
• Low-power sensor conditioning
• Gas detection
• Energy harvesting applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix HUD indicates the H-grade temperature range (-40°C to 125°C) and the TRPBF designation confirms tape and reel packaging with lead-free finish. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the quad configuration required for the design. Check datasheet specifications for thermal resistance values relevant to the PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels of precision amplification are required in a compact footprint. The quad configuration reduces board space compared to single-channel alternatives. Consider the 16-lead QFN package for thermal management and size constraints. Verify that the 20kHz bandwidth meets the signal processing requirements of the application.

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 provides four independent amplifiers. All variants share identical electrical characteristics regarding offset, drift, and supply current, differing only in channel count and package type.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC2065IUD#TRPBF serves as a functional substitute with an industrial temperature range (-40°C to 85°C). Other members of the family include LTC2063 and LTC2064 variants for single or dual channel needs. Cross-referencing requires matching the quad configuration and package style.
