AS358P-E1

Overview

The AS358P-E1 is a low power dual operational amplifier manufactured by Diodes Incorporated, housed in an 8-pin PDIP package. It features two independent, internally frequency compensated amplifiers designed for single or split supply operation. The device operates within a supply voltage range of 3V to 36V (single) or ±1.5V to ±18V (dual). Key electrical characteristics include a typical input offset voltage of 2mV, a maximum input bias current of 200nA, and a typical large signal voltage gain of 100dB. It supports a continuous output short circuit current of up to 40mA and functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Internally frequency compensated for unity gain stability
• Low supply current drain independent of power supply magnitude
• Input common mode voltage range includes ground potential
• Large output voltage swing extending from ground to VCC minus 1.5V

Applications

• Transducer amplifiers
• DC gain blocks
• Battery charger circuits
• Cordless telephone systems
• Switching power supply control loops

Procurement Notes

Verify the component marking ID matches the datasheet specifications for the PDIP-8 package. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering suffix corresponds to the correct lead-free and green molding compound requirements. Validate that the supplier provides traceability data consistent with Diodes Incorporated manufacturing standards.

Selection Notes

Select this component when a general-purpose dual op amp requires low power consumption and rail-to-ground input capability. The PDIP-8 package is suitable for through-hole prototyping or applications requiring higher thermal resistance compared to surface mount options. Consider the AS358A variant if stricter input offset voltage limits are necessary for precision applications.

Part Context

This part belongs to the AS358/358A/358B series of low power dual operational amplifiers. It is compatible with industry standard 358 pinouts and functionality. The 'E1' suffix indicates RoHS compliance without the specific 'Green' halogen-free designation associated with the 'G1' suffix. The PDIP-8 package offers distinct mechanical advantages for manual assembly or high-reliability through-hole mounting.
