LTC2054IS5#TRMPBF

Instrumentation, Op Amps, Buffer Amps Overview

The Analog Devices LTC2054IS5#TRMPBF 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 6V and guarantees specifications over the industrial temperature range of –40°C to 85°C. Key electrical parameters include a maximum input offset voltage of 3μV, an average input offset drift of 30nV/°C, and a typical input bias current of 1pA at 25°C. The device features a gain-bandwidth product of 500kHz, a slew rate of 0.5V/μs, and a DC-to-10Hz noise of 1.6μV peak-to-peak.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IS5 corresponds to the industrial temperature grade (–40°C to 85°C) and the TSOT-23 package type. Confirm that the #TRMPBF designation indicates tape and reel packaging with mouse reel compatibility. Ensure the component matches the lead-free finish requirements specified in the ordering information table.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low DC offset and drift are critical for precision measurements in space-constrained designs. The TSOT-23 package offers a low-profile solution suitable for portable applications. Consider the 150μA supply current for power budget constraints and verify that the 500kHz bandwidth meets the signal frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2054/LTC2055 family of single and dual micropower zero-drift operational amplifiers. The 'I' suffix denotes the industrial temperature grade, while 'S5' specifies the 5-lead TSOT-23 package. The family includes extended temperature variants like the MP version and high-voltage HV versions for different operating environments.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LTC2054IS5 support input signals exceeding the common mode range?

Yes, the input stage allows nearly rail-to-rail common mode signals, and signals extending beyond the allowed range do not cause output phase inversion.

What is the internal sampling frequency of the auto-zeroing circuit?

The internal sampling frequency is typically 1.0kHz, which results in clock feedthrough visible in the output spectrum.
