AMP02FS-REEL

Overview

The AMP02FS-REEL is a high accuracy instrumentation amplifier in a 16-lead SOIC package. It features laser-trimmed input offset voltage under 200 µV and output offset below 8 mV. Gain ranges from 1 to 10,000 via a single resistor. Common-mode rejection reaches 115 dB minimum. Bandwidth is 200 kHz at gain 1000. Slew rate exceeds 4 V/µs. Operating temperature spans -40°C to +85°C.

Feature Summary

• Laser trimming ensures low input offset voltage and drift for precision applications.
• Internal input protection network allows inputs to withstand overvoltage conditions without damage.
• Single external resistor sets gain across a wide range without requiring components for unity gain.
• High common-mode rejection ratio maintains signal integrity in noisy environments.

Applications

• Strain gage amplification
• Thermocouple signal conditioning
• RTD measurement circuits
• Medical instrumentation front ends

Procurement Notes

Verify the specific suffix REEL indicates tape and reel packaging when sourcing. Confirm the AMP02FS variant matches the required 16-lead SOIC form factor. Check current availability status as older precision amplifier lines may have limited stock or obsolescence notices. Ensure supply voltage requirements align with system design constraints.

Selection Notes

Select this component for applications demanding high common-mode rejection and precise gain settings. The internal protection offers robustness against transient input errors. Consider the bandwidth limitations at higher gains compared to lower gain configurations. Evaluate thermal management needs given the operating temperature range and power dissipation characteristics.

Consult manufacturer documentation for any updated versions or recommended upgrades within the same product line.

FAQ

How is the voltage gain configured?

Gain is set by a single external resistor connected between pins RG1 and RG2. No resistor is needed for unity gain.

What is the function of the Reference pin?

The Reference pin allows the output to be referenced to an external DC level, enabling offset correction or level shifting.

Does the device support overvoltage protection?

Yes, the inputs can be taken 60 V beyond either supply rail without damaging the device due to internal protection circuitry.
