OP97EP

Instrumentation, Op Amps, Buffer Amps Overview

The OP97EP is a low-power, high-precision operational amplifier manufactured by Analog Devices Inc. It serves as a low-power alternative to the industry-standard OP07, maintaining similar performance standards while utilizing only 600 μA maximum supply current. The device features an ultralow input offset voltage of 25 μV maximum and an offset voltage drift below 0.6 μV/°C. It offers very low bias current, remaining below 100 pA at 25°C and 250 pA across the extended industrial temperature range of −40°C to +85°C. With a minimum common-mode rejection of 114 dB and a power supply rejection ratio of 114 dB, it supports operating supply voltages from ±2 V to ±20 V.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'EP' against the official Analog Devices ordering guide to confirm package type and RoHS compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revision G specifications to confirm electrical characteristics match design requirements before finalizing orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the OP97EP when replacing OP07, AD725, OP05, OP12, or PM1012 amplifiers in existing designs to reduce power dissipation without sacrificing precision. Consider this component for circuits requiring minimal external offset trimming due to its tightly trimmed offset voltage. Evaluate the device for applications needing high input impedance and low noise performance over wide temperature ranges where standard precision amplifiers consume excessive power.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP97 belongs to the OP97 series of low-power operational amplifiers designed by Analog Devices. It is pin-compatible with the OP07, allowing direct substitution in many legacy circuits. The series includes variants such as the OP97E, OP97F, and their RoHS-compliant counterparts like the OP97EPZ. This family targets applications demanding high accuracy with reduced power consumption compared to traditional precision op amps.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OP97EP can replace OP07, AD725, OP05, OP12, and PM1012 amplifiers. It may substitute 741-type amplifiers if nulling circuitry is removed.
