LTC2054HVHS5#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The Analog Devices LTC2054HVHS5#TRPBF is a single-channel micropower zero-drift operational amplifier housed in a 5-lead plastic TSOT-23 package. It operates from a supply voltage range of 2.7V to ±5.5V with a maximum total supply of 12V. Key electrical specifications include a typical input offset voltage of 5µV, an average drift of 30nV/°C, and a typical input bias current of 3pA. The device features a gain-bandwidth product of 500kHz, a slew rate of 0.5V/µs, and rail-to-rail output swing. It guarantees operation over the extended temperature range of –40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HV designation ensures compatibility with higher voltage supplies up to 12V total. Ensure the HS5 package code matches the required TSOT-23 footprint on the PCB layout. Check that the H grade meets the necessary -40°C to 125°C operating temperature requirements for the target environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC accuracy without external trimming. The HV variant supports dual supplies up to ±5.5V, suitable for wider signal swings compared to standard versions. Consider the TSOT-23 package for space-constrained designs where surface mount assembly is preferred. Evaluate the 500kHz bandwidth against signal frequency needs to ensure adequate gain-bandwidth product.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2054/LTC2055 family of micropower zero-drift operational amplifiers. It shares architectural similarities with the LTC2054C/I/H variants but offers extended voltage handling capabilities. The family is designed for precision sensing applications where low offset and drift are critical. It complements other Linear Technology precision amplifiers like the LTC1050 series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC2054HVIS5#TRPBF: Same package and temperature range but lower voltage rating (max 7V). LTC2054HVCS5#TRPBF: Lower temperature grade (0°C to 70°C) with same voltage rating. LTC2054HS5#TRPBF: Standard voltage rating (max 7V) with extended temperature range.
