LTC2064HDD#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2064HDD#TRPBF is a dual zero-drift operational amplifier from Analog Devices, housed in a 10-lead (3mm × 3mm) plastic DFN package. It operates within a supply voltage range of 1.7V to 5.25V and supports an extended temperature range of –40°C to 125°C. The device features a maximum input offset voltage of 10µV and a drift of 0.05µV/°C over the full temperature range. Supply current is limited to 4µA per amplifier, with shutdown current below 500nA. It includes rail-to-rail input/output capability and integrated EMI filtering.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Self-calibrating architecture eliminates low-frequency noise and minimizes input offset voltage drift for high precision.
• Integrated EMI filter provides significant rejection against radio frequency interference at common wireless frequencies.
• Optimized shutdown mode significantly reduces power consumption in duty-cycled applications while minimizing charge loss during power-up.

Instrumentation, Op Amps, Buffer Amps Applications

• Low-power sensor conditioning
• Portable instrumentation systems
• Gas detection circuits
• Medical instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'H' grade designation matches the required –40°C to 125°C operating temperature range for your application environment. Ensure the 10-lead DFN footprint aligns with your PCB layout constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for dual-channel applications requiring ultra-low drift and minimal quiescent current. The H-grade variant is necessary for environments exceeding 85°C. Consider the DFN package thermal characteristics and ensure adequate PCB copper area for heat dissipation if operating near maximum junction temperatures.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2063/LTC2064/LTC2065 family of microprecision zero-drift amplifiers. While the LTC2063 is single-channel and the LTC2065 is quad-channel, the LTC2064 specifically provides two independent channels in a compact form factor. All variants share identical electrical performance characteristics regarding offset, bias current, and bandwidth.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC2064IDD#TRPBF serves as the industrial grade (-40°C to 85°C) alternative. For single-channel requirements, consider the LTC2063 series. For quad-channel needs, the LTC2065 series is the direct functional equivalent within the same package technology.
