BA10324A

Overview

The BA10324A is a monolithic quad operational amplifier featuring internal phase compensation. It supports single power supply operation from 3V to 32V or dual supplies of ±1.5V to ±16V. The device allows ground-level common-mode input voltage and differential input up to the power supply level. Key electrical characteristics include a typical quiescent current of 0.6mA, maximum input offset voltage of 7mV, and typical open-loop voltage gain of 100dB.

Feature Summary

• Ground sensing capability allowing common-mode input voltage to operate from the ground level.
• Wide operating power supply voltage range supporting both single and dual supply configurations.
• Low current dissipation with typical quiescent current of 0.6mA.
• Built-in four operational amplifiers with internal phase compensation.

Applications

• Ground sensing type pre-amplifiers
• Active filters
• DC amplifiers
• Pulse generators

Procurement Notes

Verify package suffixes (e.g., AF for SOP, AFV for SSOP-B) against mechanical requirements. Confirm RoHS compliance status for specific manufacturing lots. Ensure thermal management aligns with absolute maximum ratings for the selected package type. Consult manufacturer documentation for automotive or high-reliability application approvals.

Selection Notes

Select based on required channel count and package style. The BA10324A offers quad channels in DIP-14, while variants provide surface mount options. Consider the low quiescent current for battery-powered designs. Verify that the ground-sense input range meets system signal requirements. Check compatibility with existing circuit layouts due to industry-standard pinouts.

Part Context

This component belongs to ROHM's standard IC operational amplifier series. It is designed as a general-purpose solution for administrative and industrial applications. The device is compatible with model 324 operational amplifiers from other manufacturers, facilitating direct replacement in existing designs without schematic modifications.

Replacement Considerations

Compatible with model 324 operational amplifiers of other manufacturers. Verify pinout compatibility before substitution.
