AS358MTR-G1

Overview

The AS358MTR-G1 is a low power dual operational amplifier manufactured by Diodes Incorporated. It features two independent, high gain amplifiers with internal frequency compensation for unity gain stability. The device operates from a single supply voltage ranging from 3V to 36V or split supplies of ±1.5V to ±18V. Key electrical characteristics include a typical input offset voltage of 2mV, an input bias current of 20nA, and a large signal voltage gain of 100dB. It supports an output short circuit current of up to 40mA and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Internally frequency compensated for unity gain stability
• Wide power supply voltage capability supporting single and split configurations
• Input common mode voltage range includes ground potential
• Large output voltage swing extending down to the negative rail

Applications

• Battery charger circuits
• Cordless telephone systems
• Switching power supply control loops

Procurement Notes

Verify that the component matches the specific package type indicated in the ordering information, as the AS358 series is available in multiple formats including SO-8, TSSOP-8, MSOP-8, PDIP-8, and TDIP-8. Confirm RoHS compliance status and ensure the marking ID aligns with the manufacturer's documentation for the specific revision. Check for any assembly site changes documented in Product Change Notices prior to finalizing procurement.

Selection Notes

Select this component when designing circuits requiring low power consumption with a wide single-supply operating range. The internal frequency compensation simplifies design for unity gain applications without external components. Consider the input offset voltage specifications if precision DC amplification is required, noting that the 'A' variant offers tighter tolerances than the standard version.

Part Context

This part belongs to the AS358/358A/358B family of low power dual operational amplifiers. It is designed as a compatible replacement for industry-standard 358 devices. The M suffix indicates the SO-8 surface mount package, while the TR-G1 designation specifies tape and reel packaging with lead-free and green molding compound compliance.
