Hot-selling and scarce FDA2100LV PWM digital input power amplifier IC QFP spot stock

Product Descriptions

The FDA2100LV is a new BCD technology dualbridge class D amplifier,specially intended for carradio applications .

Thanks to the BCD6-SOI (Silicon On Insulation)technology it is possible to integrate a highperformance D/A converter together with powerfulMOSFET output amplifier working in class D,toget outstanding efficiency with respect to thestandard class AB .

The D/A conversion on board allows theperformance to reach an outstanding 110 dB S/Nratio with 105 dB of dynamic range .The feedbackloop includes the output L-C low-pass filter,allowing superior frequency response linearityand lower distortion independently of the inductorand capacitor quality.
