AS358P-G1

Overview

The AS358P-G1 is a dual operational amplifier from Diodes Incorporated, designed for single-supply operation with split supply capability. It features two independent, high-gain channels with internal frequency compensation. The device operates within a voltage range of 3V to 36V and draws a low power supply current of approximately 700µA. Key electrical characteristics include a maximum input offset voltage of 7mV and an input bias current of 200nA. It provides a typical common-mode rejection ratio of 70dB and supports output currents up to 40mA per channel.

Feature Summary

• Internally frequency compensated for stability in standard configurations
• Low power supply current drain independent of supply voltage magnitude
• Compatible with industry standard LM358 pinouts and functions

Applications

• Transducer amplifiers
• DC gain blocks
• Conventional operational amplifier circuits

Procurement Notes

Verify the package type upon ordering, as the suffix 'P' typically indicates a DIP-8 housing but datasheet variations exist. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Check for obsolescence notices, as some variants may be discontinued while others remain active. Ensure the specific lot date code meets project requirements before finalizing procurement.

Selection Notes

Select this component when a general-purpose, low-power dual op-amp is required for single-supply applications. It serves as a direct replacement for standard LM358 devices where DIP-8 packaging is preferred. Consider the 7mV max offset voltage and 200nA bias current limits against circuit sensitivity requirements. Verify that the 36V maximum supply voltage aligns with system power rails.

Part Context

This part belongs to the AS358 series of low-power dual operational amplifiers manufactured by Diodes Incorporated. The series is engineered to offer cost-effective performance for non-specialized analog signal processing tasks. It maintains functional compatibility with legacy designs while providing modern manufacturing standards.

Replacement Considerations

The AS358P-G1 is functionally compatible with the industry-standard LM358 in DIP-8 packages. Other Diodes Incorporated variants such as the AS358AMTR-G1 (SOIC) or AS358MMTR-G1 (MSOP) share similar electrical characteristics but differ in physical footprint.
