Overview
The FDA2100BLV is a dual bridge Class D audio amplifier designed for automotive radio applications. It features integrated digital-to-analog conversion and supports I2S and TDM digital inputs at 3.3V or 1.8V logic levels. The device delivers up to 180W per channel into a 4-ohm load in stereo mode, or 300W in mono bridged configuration. It operates on a supply voltage range of 6V to 35V and includes input sampling frequencies of 44.1kHz and 48kHz. The component is housed in a 64-pin TQFP-EP package.
Feature Summary
- AEC-Q100 qualified for automotive reliability standards
- Integrated 105 dB digital-to-analog conversion capability
- Supports I2S and TDM digital input interfaces
- Includes internal digital signal processing for interpolation and noise reduction
Applications
- Automotive radio systems
- Car audio amplification
- Digital audio processing units
Procurement Notes
Verify the specific suffix (BLV) matches the required package and temperature grade. Confirm that the digital interface requirements align with the system's I2S or TDM configuration. Ensure the power supply design accommodates the specified voltage range and output power demands. Check for AEC-Q100 compliance if automotive qualification is mandatory for the end application.
Selection Notes
Select this component when a high-power Class D solution with direct digital input is required. It eliminates external DACs by providing integrated conversion. Consider the 64-pin TQFP-EP package for thermal management and PCB space constraints. Verify compatibility with the host processor's digital audio interface before finalizing the design.
Part Context
This part belongs to STMicroelectronics' FDA2100 series of digital audio amplifiers. The series is engineered specifically for the automotive sector, offering high efficiency and sound quality. The BLV variant denotes the specific pinout and packaging configuration within this product line.
Replacement Considerations
Check for FDA2100LV as a potential alternative, though verify package and feature parity. Ensure any substitute maintains AEC-Q100 qualification and similar power output specifications for automotive use.
