SSM2131P

Overview

The SSM2131P is a high-speed audio operational amplifier manufactured by Analog Devices Inc. It features a JFET input stage and is housed in an 8-pin PDIP package. Key electrical specifications include a maximum offset voltage of 6000 µV, a single functional channel configuration, and a symmetric slew rate of 50 V/µs. The device is designed for ultra-low distortion performance in professional audio applications.

Feature Summary

• JFET input architecture for low noise operation
• High slew rate capability for fast signal response
• Ultra-low distortion characteristics for audio fidelity

Applications

• Professional audio mixing consoles
• High-fidelity preamplifier stages
• Audio processing circuits requiring low distortion

Procurement Notes

Verify the obsolete status of the SSM2131P with authorized distributors or manufacturers before procurement planning. Confirm availability through secondary market channels if direct supply is discontinued. Ensure compatibility with existing PCB footprints and thermal management requirements during replacement evaluation.

Selection Notes

Select this component for applications prioritizing low distortion and high speed in audio signal paths. Consider the JFET input characteristics for impedance matching needs. Evaluate the PDIP8 package constraints against available board space and assembly methods. Verify that the 50 V/µs slew rate meets the dynamic range requirements of the target audio system.

Part Context

The SSM2131P belongs to the SSM series of operational amplifiers from Analog Devices Inc., specifically engineered for audio applications. It represents a legacy product line focused on high-performance analog signal processing. The 'P' suffix denotes the plastic dual in-line package variant, distinguishing it from surface-mount options within the same functional family.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Consult Analog Devices cross-reference tools or authorized distributors for parametrically equivalent alternatives suitable for audio amplifier designs.
