Overview
The BA15218 is a monolithic integrated circuit containing two built-in low-noise, low-distortion operational amplifiers with internal phase compensation. It supports single power supplies from 4V to 32V or dual supplies from ±3V to ±16V. Key electrical characteristics include a typical slew rate of 3V/µs, gain-bandwidth product of 10MHz, and input offset voltage of 0.5mV. The device features high gain (110dB), low distortion (0.0015% THD), and operates within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Low noise level suitable for audio applications
- High slew rate and wide bandwidth
- Compatible with standard dual op-amp pinouts
Applications
- Audio visual equipment
- Office automation equipment
- Communications devices
- Electrical appliances
Procurement Notes
Verify the specific package suffix required for your design: BA15218 for DIP-8, BA15218F for SOP-8, or BA15218N for SIP-8. Confirm that the selected variant meets the thermal dissipation requirements for your intended operating environment. Ensure peripheral conditions align with the absolute maximum ratings provided in the official datasheet before finalizing procurement.
Selection Notes
Select this component when a dual operational amplifier with high slew rate and low noise is required. It serves as a direct replacement for standard models like the 4558 and 4560 due to identical pin connections. Consider its compatibility with digital system 5V single power supplies if applicable to your circuit architecture.
Part Context
This part belongs to ROHM's Standard ICs portfolio, specifically designed for general-purpose analog signal conditioning. It addresses applications requiring reliable performance in consumer electronics and office automation. The series includes variants tailored for different mounting styles while maintaining consistent electrical specifications across the family.
Replacement Considerations
The BA15218 is explicitly noted as compatible with the 4558 and 4560 models due to identical pin connections. Verify that substitute components match the required slew rate and noise specifications for critical audio or precision applications.
FAQ
