AMP02EP

Overview

The AMP02EP is a high-accuracy instrumentation amplifier housed in an 8-lead plastic DIP package. It features laser-trimmed input offset voltage with a maximum of 100 µV at 25°C and drift under 2 µV/°C. Gain is programmable from 1 to 10,000 via a single external resistor, maintaining gain accuracy better than 0.5% at G=1000. The device includes internal input overvoltage protection allowing inputs to exceed supply rails by 60 V. It operates on dual supplies ranging from ±4.5 V to ±18 V with a typical supply current of 5.6 mA.

Feature Summary

• Laser-trimmed precision architecture ensures low input offset voltage and minimal temperature drift for high measurement accuracy.
• Integrated input protection network withstands significant overvoltage conditions without damage, enhancing system robustness.
• Single-resistor gain setting simplifies circuit design while maintaining wide bandwidth across the entire gain range.

Applications

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

Procurement Notes

Verify the specific suffix EP corresponds to the 8-lead plastic DIP package variant when sourcing. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure power supply decoupling meets the datasheet recommendations to maintain the stated PSR specifications. Check for ESD sensitivity precautions during handling and assembly processes.

Selection Notes

Select this component when high DC accuracy and stability are critical for low-level signal amplification. The wide gain range allows flexibility in sensor interface design without changing the amplifier topology. Consider the internal protection features if the application environment poses risks of transient overvoltages or incorrect wiring.

Part Context

The AMP02 series represents Analog Devices' first precision instrumentation amplifier available in an 8-lead package. It utilizes a proprietary thin-film resistor process to achieve tight gain temperature coefficients. The EP variant specifically denotes the plastic DIP packaging option within the broader AMP02 family, which also includes ceramic and SOIC configurations.

Replacement Considerations

AMP02FP: Offers similar functionality but with higher offset voltage specifications (200 µV max) compared to the EP variant.
