Overview
The BA4560 is a dual operational amplifier featuring a gain-bandwidth product of 10 MHz and a slew rate of 4 V/ms. It provides high output current, approximately double that of the BA4558. Key electrical parameters include an input offset voltage of 0.5 mV typical (6.0 mV max), input bias current of 50 nA typical (500 nA max), and common-mode rejection ratio of 90 dB typical. The device operates within a power supply range of ±18 V and supports an operating temperature from -40°C to +85°C.
Feature Summary
- Built-in output short-circuit protection circuit
- Internal phase correction for stability
- No latch-up effect under stress conditions
- Wide common-mode and differential voltage range
Applications
- Active filters
- Audio amplifiers
- Voltage-controlled oscillators (VCOs)
Procurement Notes
Verify package type compatibility during sourcing, as the BA4560 family includes DIP-8, SOP-8, and SIP-8 variants. Confirm RoHS compliance status with the supplier, as suffixes like 'E2' or 'GE2' indicate specific environmental certifications. Ensure the selected variant matches the required thermal dissipation characteristics for the target PCB layout.
Selection Notes
Select the BA4560 when higher output drive capability than the BA4558 is required. Choose the SOP-8 variant (BA4560F) for surface-mount applications requiring compact footprints. Consider the wide common-mode input range and low noise characteristics for precision signal conditioning tasks in audio or sensor interfaces.
Part Context
The BA4560 belongs to ROHM's standard dual operational amplifier series, designed as a high-performance alternative to legacy bipolar op-amps. It shares functional similarities with the UPC4560 but offers improved slew rates and output current capabilities. The family encompasses multiple package options to support diverse manufacturing and thermal requirements.
Replacement Considerations
The UPC4560 is a documented functional substitute offering similar dual op-amp performance. Verify pinout compatibility and ensure the replacement meets the specific power supply and thermal constraints of the original design.
