Overview
The BD27400GUL-E2 is a single-channel Class D speaker amplifier designed for mobile audio applications. It operates on a power supply voltage range of 2.5V to 5.5V and delivers up to 2.5W output into a 4Ω load, or 0.85W into an 8Ω load. The device features a maximum gain of 26dB and requires no external LC filter for speaker output. Standby current is typically 0.1µA with a startup time of 3ms.
Feature Summary
- Eliminates the need for external LC filters at the speaker output
- Provides high efficiency and low power consumption suitable for battery-driven devices
- Features extremely low standby current with rapid recovery from standby mode
Applications
- Mobile phones
- Portable electronic devices
- Battery-powered audio products
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest documentation to confirm package type and RoHS compliance status. Ensure the application environment remains within the specified operating temperature range and voltage limits. Confirm that the intended use case does not involve automotive equipment, as this standard-grade component is explicitly excluded from such applications.
Selection Notes
Select this component for designs requiring a compact, single-channel audio solution without complex output filtering. It is appropriate for systems where minimizing BOM count and board space is critical. The adjustable gain via external resistors offers flexibility in signal chain design. Verify that the target load impedance matches the rated output power specifications for optimal performance.
Part Context
This part belongs to ROHM's line of low-voltage Class D amplifiers tailored for portable electronics. It utilizes digital switching technology to achieve higher efficiency compared to linear amplifiers. The VCSP50L1-9 package allows for small footprint implementation. The product is classified as a standard grade item with a recommended status for new designs.
Replacement Considerations
Consult official substitution lists for verified alternatives. Generic Class D amplifiers may differ in output power, filter requirements, or standby current characteristics.
