LB4310AAPG

Overview

The LB4310AAPG is a dual general-purpose operational amplifier manufactured by Diodes Incorporated. It features two independent circuits within an 8-SOP package, designed for analog signal processing tasks. The device operates with a supply voltage span ranging from 3 V to 36 V and supports an output current of 40 mA per channel. It functions reliably across an operating temperature range of -40°C to 105°C (TA). Key electrical characteristics include a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/μs, with an input bias current specified in official documentation.

Feature Summary

• Dual circuit configuration for general-purpose analog signal processing
• Wide single-supply voltage operation capability
• Surface-mount 8-SOP packaging for compact integration

Applications

• Analog signal conditioning
• General-purpose amplification
• Buffer applications

Procurement Notes

Verify the manufacturer designation as Diodes Incorporated, noting the historical acquisition of Pericom. Confirm the package type is 8-SOP (SOIC) with a 3.90mm width. Ensure the operating temperature range covers -40°C to 105°C. Cross-reference the part number suffix 'PG' for lead-free compliance if required by your assembly specifications.

Selection Notes

Select this component when a dual op-amp solution is required for low-frequency applications given its 1 MHz gain-bandwidth product. It is suitable for designs needing wide supply voltage flexibility up to 36 V. Consider the 8-SOP footprint constraints and the 40 mA output current limit relative to your load requirements.

Part Context

This component belongs to the linear amplifier category, specifically under instrumentation and operational amplifiers. Originally associated with Pericom before its acquisition by Diodes Incorporated, it serves as a standard general-purpose amplifier. The LB4310 series provides a cost-effective solution for basic analog processing needs in consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the Diodes Incorporated portfolio or other manufacturers offering dual op-amps with similar 3V-36V supply ranges and 8-SOP packages. Verify that replacement parts meet the same -40°C to 105°C temperature rating and 1 MHz bandwidth specifications.
