OP497FP

Instrumentation, Op Amps, Buffer Amps Overview

The OP497FP is a quad precision operational amplifier manufactured by Analog Devices Inc., housed in a 14-lead Plastic Dual In-Line Package (N-14). It features a maximum offset voltage of 80 µV and drift of 1.0 µV/°C at 25°C, with input bias currents up to 150 pA. The device operates on supplies from ±2 V to ±20 V, drawing 625 µA per channel. Key electrical parameters include a gain-bandwidth product of 500 kHz, slew rate of 0.15 V/µs, and common-mode rejection ratio exceeding 114 dB.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Utilizes superbeta input stage technology with bias current cancellation to maintain picoampere-level input bias currents across the full operating temperature range.
• Provides high open-loop gain linearity and extremely low noise density for accurate signal processing in high-gain applications.
• Operates effectively with supply voltages as low as ±2 V, making it suitable for battery-powered systems while maintaining high power supply rejection.

Instrumentation, Op Amps, Buffer Amps Applications

• Strain gage and bridge amplifiers
• High stability thermocouple amplifiers
• Instrumentation amplifiers
• Photocurrent monitors
• Long-term integrators and filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific grade suffix (F or G) required for your design, as these determine the maximum offset voltage and bias current limits. Confirm that the N-14 package option matches your PCB footprint requirements. Ensure the selected component meets RoHS compliance standards if mandated by your manufacturing process. Cross-reference the ordering guide to confirm availability and lead times through authorized distributors.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the OP497FP when precise low-frequency signal conditioning is required with minimal drift over time. The F-grade offers tighter offset voltage specifications compared to the G-grade. Consider the low supply current for power-constrained designs. Evaluate the trade-off between the slow slew rate and the high DC precision offered by this device family for your specific bandwidth needs.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP497 belongs to a family of precision quad operational amplifiers designed for applications demanding exceptional DC accuracy. It shares architectural similarities with the dual-channel OP297 and single-channel OP97. The FP variant specifically denotes the plastic DIP packaging, distinguishing it from surface-mount options like the FS series. This component is widely used in industrial instrumentation where stability and low leakage are critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same package include the OP497GP and OP497GS variants, though their electrical specifications differ slightly. For surface-mount implementations, the OP497FS serves as a functional equivalent in the SOIC package. Verify that any substitute maintains the required input bias current and offset voltage characteristics for your application.
