Overview
The BA4558N is a dual operational amplifier manufactured by ROHM Semiconductor, housed in an 8-pin SIP package. It features internal phase compensation and low power consumption of approximately 50mW. Key electrical parameters include a maximum input offset voltage of 6.0 mV, a typical high-amplitude voltage gain of 100 dB, and a slew rate of 1.0 V/ms. The device supports a power supply voltage range up to ±18 V and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Built-in output short-circuit protection circuit
- Internal phase compensation for stability
- No latch-up characteristic
- Wide common-mode and differential voltage range
Applications
- Active filters
- Audio amplifiers
- Voltage-controlled oscillators (VCOs)
Procurement Notes
Verify the specific ordering suffix and package type against the manufacturer's current datasheet to ensure compatibility with the 8-pin SIP form factor. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.
Selection Notes
Select this component for applications requiring a dual op-amp with internal frequency compensation and low power dissipation. Ensure the design accommodates the specified input bias current and offset voltage limits. Verify that the required operating temperature range falls within the -40°C to +85°C specification and that the power supply voltage does not exceed the absolute maximum ratings.
Part Context
This part belongs to the BA4558 series, which includes variants like the BA4558 (DIP) and BA4558F (SOP). All share the same monolithic IC architecture but differ in packaging. The BA4558N specifically utilizes an 8-pin SIP package, distinguishing it from the standard DIP and SOP options while maintaining identical electrical performance characteristics.
Replacement Considerations
Compatible substitutes include other dual operational amplifiers with similar pinouts and electrical specifications, such as the LM833 or TL082, provided they meet the required power supply and performance criteria.
