MAX297ESA

Overview

The MAX297ESA is a dual, low-power, precision operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a supply voltage range of 2V to 40V and operates within a temperature range of -40°C to +85°C. The device provides a gain-bandwidth product of 500kHz and a slew rate of 0.15V/µs. Input offset voltage is typically 25µV with a maximum of 100µV. Input bias current is 20pA. It is housed in an 8-SOIC (0.150", 3.90mm Width) package.

Feature Summary

• Dual precision operational amplifier architecture
• Low input bias current specification
• Wide single or split supply voltage operation
• Rail-to-rail output capability

Applications

• Precision sensor signal conditioning
• Active filtering applications
• High-impedance buffer circuits

Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Confirm availability status as distribution data may reflect obsolete inventory levels rather than current manufacturing capacity.

Selection Notes

Select this component for designs requiring high input impedance and precision amplification within a wide voltage range. Ensure the thermal performance of the SOIC package meets the system's dissipation requirements under maximum load conditions.

Part Context

This part belongs to the OP297/MAX297 family of dual precision op-amps. It serves as a general-purpose solution for analog signal processing where low noise and high accuracy are required without the complexity of chopper-stabilized amplifiers.

Replacement Considerations

Direct pin-compatible alternatives include the OP297 series from Analog Devices. Verify that substitute parts meet the specific input bias current and offset voltage requirements of the original design.
