LTC2050IS6#TRMPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2050IS6#TRMPBF is a zero-drift operational amplifier housed in a 6-lead plastic TSOT-23 package. It operates from a single supply ranging from 2.7V to 6V with typical current consumption of 800µA. Key electrical specifications include a maximum input offset voltage of 3µV, an average input offset drift of 30nV/°C, and a gain bandwidth product of 3MHz. The device features rail-to-rail output swing, high common mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) exceeding 130dB, and an internal sampling frequency of 7.5kHz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Utilizes auto-zeroing architecture to achieve near-zero DC offset and drift across temperature and supply variations
• Provides rail-to-rail output capability capable of driving loads as low as 2kΩ to both supply rails
• Includes an active-low shutdown pin that reduces supply current significantly when deactivated
• Features extended common-mode input range extending from the negative supply up to typically 1V below the positive supply

Instrumentation, Op Amps, Buffer Amps Applications

• Thermocouple amplifiers
• Electronic scales
• Medical instrumentation
• Strain gauge amplifiers
• High resolution data acquisition systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 units. Confirm the IS6 designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 6-lead TSOT-23 package matches the required footprint for the target PCB layout. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision without external trimming. The 6-lead SOT-23 package offers a compact solution compared to the 8-lead SO-8 variant which includes additional NC pins. Consider the 800µA supply current for power-sensitive designs. Verify that the single supply operation range of 2.7V to 6V aligns with the system voltage constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LTC2050 family of zero-drift operational amplifiers designed for high-precision analog signal conditioning. The family includes variants such as the LTC2050HV for dual supply operations and different package options like the 5-lead TSOT-23 and 8-lead SO-8. The IS6 variant specifically targets industrial environments with a defined operating temperature range.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the shutdown pin function on the 6-lead package?

The shutdown pin is active low. When pulled low, the device enters shutdown mode, stopping all clocking and reducing supply current to approximately 10µA while placing inputs and output in a high impedance state.

What causes clock feedthrough in this zero-drift amplifier?

Clock feedthrough results from the internal auto-zeroing circuitry operating at a typical frequency of 7.5kHz. It manifests as residue noise at the output spectrum due to charge injection and internal capacitor settling.
