Overview
The FDA802S-VYY is a dual-bridge Class-D automotive power amplifier manufactured by STMicroelectronics. It operates on a supply voltage range of 5.5V to 18V and delivers up to 540W of output power. The device features integrated 110 dB D/A conversion and supports I2S and TDM digital inputs at 3.3V or 1.8V levels. It is housed in a 64-LQFP-EP (10x10) package with an exposed pad for thermal management. Qualified under AEC-Q100 standards, it functions within a temperature range of -40°C to 105°C.
Feature Summary
- Integrated high-resolution digital-to-analog conversion with 110 dB performance
- Supports I2S and TDM digital audio interfaces
- AEC-Q100 qualified for automotive reliability
Applications
- Car radio systems
- Automotive infotainment amplifiers
- Digital audio processing units in vehicles
Procurement Notes
Verify the specific suffix 'VYY' against official STMicroelectronics documentation to confirm pinout and packaging details. Ensure compatibility with the required digital input voltage levels (1.8V or 3.3V). Confirm that the design accounts for the thermal requirements of the 64-LQFP-EP package during operation.
Selection Notes
Select this component for applications requiring high-power Class-D amplification with direct digital audio inputs. It is suitable for designs needing integrated DAC functionality to reduce external component count. Verify that the system power supply can support the specified voltage range and that the PCB layout accommodates the large exposed pad for heat dissipation.
Part Context
This part belongs to the FDA802 series of dual bridge Class-D amplifiers designed using advanced BCD technology. The series is specifically intended for car radio applications, offering robust performance and integration for modern automotive audio systems.
Replacement Considerations
Check for FDA802 variants with different suffixes if alternative packaging or minor electrical differences are acceptable. Ensure any substitute maintains AEC-Q100 qualification and compatible digital interface support.
