AS358MTR-E1

Overview

The AS358MTR-E1 is a low power dual operational amplifier manufactured by Diodes Incorporated. It features two independent, internally frequency compensated amplifiers designed for single or split power 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, an input bias current of 20nA, and a large signal voltage gain of 100dB. The supply current is typically 0.5mA at 5V. It supports rail-to-rail output swing capability down to ground and includes short circuit protection.

Feature Summary

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

Applications

• Transducer amplifiers
• DC gain blocks
• Battery chargers
• Cordless telephones
• Switching power supplies

Procurement Notes

Verify the specific package type and RoHS compliance status against the manufacturer's latest documentation before procurement. Confirm that the ordering suffix matches the required tape and reel packaging format. Ensure the component meets environmental directives such as RoHS 2 and RoHS 3 if applicable to your manufacturing region. Cross-reference the datasheet revision to confirm all electrical parameters align with your design requirements.

Selection Notes

Select this component when a general-purpose dual op-amp with low power consumption is required for single-supply applications. It is suitable for circuits where the input common-mode voltage must include ground. Consider the SO-8 surface mount package for compact designs. Verify that the input offset voltage and bias current specifications meet the precision requirements of the target application compared to higher-performance alternatives.

Part Context

This part belongs to the AS358/358A/358B series of low power dual operational amplifiers. The 'M' in the model number indicates the SO-8 package variant. The 'E1' suffix denotes RoHS compliance. The series is compatible with industry standard 358 devices but offers improved low-power characteristics. It is distinct from the AS358A which has stricter offset voltage limits and the AS358B which is available in TSSOP-8 packages.

Replacement Considerations

AS358M-G1 is listed as an alternative green molding compound version in the same package.
