LTC2054HVCS5#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The Analog Devices LTC2054HVCS5#TRPBF is a single-channel, low-power zero-drift operational amplifier housed in a 5-lead plastic TSOT-23 package. It operates from a supply voltage range of 2.7V to 11V and supports dual supplies up to ±5.5V. Key electrical specifications include a maximum input offset voltage of 5μV and an offset drift of 30nV/°C over the industrial temperature range. The device features a gain-bandwidth product of 500kHz, a typical common mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 130dB, and a typical input bias current of 1pA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the HV designation aligns with the required supply voltage headroom for your application. Ensure the TSOT-23 package dimensions match your PCB footprint constraints. Cross-reference the manufacturer's latest documentation for any updates to lead-free finishing or marking codes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC accuracy without external trimming. The HV variant is necessary if the system supply exceeds 7V. Consider the 500kHz bandwidth limit for signal frequency requirements. Evaluate the 150μA supply current against strict power budget constraints compared to standard op amps.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2054/LTC2055 family of micropower zero-drift amplifiers. The 'HV' suffix denotes the high-voltage version capable of handling higher supply potentials than the standard LTC2054. The 'S5' indicates the 5-lead TSOT-23 package, offering a compact solution for space-constrained designs.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the input common mode voltage range?

The input common mode voltage ranges from the negative supply up to typically 0.5V below the positive supply.

Does the device exhibit output phase inversion?

No, signals extending beyond the allowed input common mode range do not cause output phase inversion.
