AS2348M8-13

Overview

The AS2348M8-13 is a dual-channel CMOS operational amplifier from Diodes Incorporated, housed in an MSOP-8 package. It features rail-to-rail input and output capabilities with extended common-mode voltage range up to 300mV beyond the supply rail. The device operates on single supplies from 1.6V to 5.5V or dual supplies of ±0.8V to ±2.5V. Key electrical parameters include a gain bandwidth product of 1MHz, typical supply current of 70μA per channel, low input offset voltage of 0.5mV, and ultra-low input bias current of 1pA.

Feature Summary

• Rail-to-rail input and output operation with extended common-mode voltage capability
• Ultra-low input bias current suitable for precision applications
• Low noise density and low input offset voltage drift
• Unity-gain stable with capacitive loads up to 100pF

Applications

• Active filters
• Sensor interfaces
• Photodiode amplification
• Medical instrumentation
• Portable equipment

Procurement Notes

Verify the specific ordering suffix 'M8' corresponds to the MSOP-8 package configuration required for your design. Confirm that the tape and reel quantity matches your production needs. Ensure compatibility with RoHS and halogen-free environmental standards as specified by the manufacturer. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when designing circuits requiring low power consumption alongside high precision. The wide operating temperature range supports harsh environment applications. Consider the unity-gain stability limit when driving capacitive loads. Evaluate the low input bias current benefits for high-impedance signal sources.

Part Context

This part belongs to the AS348/AS2348 family of low noise, low power operational amplifiers. The AS2348 variant specifically provides dual-channel functionality within industry-standard packages including MSOP-8 and SO-8. It complements the single-channel AS348 offering expanded processing capabilities in compact form factors.

Replacement Considerations

Direct substitutes within the same family include the AS2348S-13 (SO-8 package). Verify pinout compatibility and electrical specifications match before substitution.
