Overview
The FDA901-VYY is a quad bridge Class-D automotive power amplifier manufactured by STMicroelectronics. It operates in LQFP64 (exposed pad up) packaging and supports I2S/TDM digital inputs with integrated 110 dB D/A conversion. The device delivers high output power, reaching 4 x 50 W on 4 Ω loads at 15.2 V, and maintains 93% efficiency. It features low voltage operation down to 6 V for start-stop compatibility, CISPR25 Class V EMI compliance, and real-time load current monitoring via I2C and TDM interfaces.
Feature Summary
- Integrated 110 dB D/A conversion with idle tones free DAC
- Low radiation function (LRF) and CISPR25 Class V compliance
- Real-time load current monitoring on I2C and TDM data lines
- Innovative feedback topology including the output LC filter
Applications
- Car radio automotive applications
- Start-stop engine compatible audio systems
- Single DIN car-radio box installations
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing method. The FDA901-VYY designation corresponds to tray packing, while the FDA901-VYT variant utilizes tape and reel packaging. Ensure that the selected package type aligns with the intended manufacturing assembly process before finalizing procurement orders.
Selection Notes
Select this component for designs requiring fully digital Class-D amplification with integrated signal processing. It is suitable for applications demanding high immunity to GSM interference and strict EMI limits. The device supports various load configurations, including 4x4Ω, 4x2Ω, and parallel setups, making it adaptable to different speaker impedance requirements.
Part Context
This part belongs to the FDA901 family of BCD technology quad bridge Class-D amplifiers. It is designed specifically for automotive environments, offering high integration levels that minimize external component count. The family includes variants with different packing options to suit diverse production line requirements.
Replacement Considerations
The FDA901-VYT serves as a direct functional substitute with identical electrical characteristics but differs in packing format, utilizing tape and reel instead of trays.
