Datasheet Analog Sound Processor Series 6ch Sound Processor for High-Quality Audio with Built-in Advanced Switch BD34602FS-M Description Key Specifications BD34602FS-M is a 6ch independent volume system. It Total harmonic distortion : 0.0004% is designed to have high-quality sound by improving the Maximum input voltage : 2.35Vrms(Typ) op-amp and optimizing the design layout. In addition, it Maximum output voltage : 2.35Vrms(Typ) is compatible, same package and it has common control Output noise voltage : 1.3Vrms(Typ) with BD3461FS, therefore replacement from BD3461FS Residual output noise voltage : 1.3Vrms(Typ) is easy. Ripple rejection : 80dB (Typ) Operating temperature range : -40C to +85C Features (Note 1) AEC-Q100 Qualified Advanced switch circuit can reduce the switching pop noise during volume attenuation Package W(Typ) x D(Typ) x H(Max) Built-in 6ch independent volume circuit available with SSOP-A24 10.00mm x 7.80mm x 2.10mm changing by 1dB/Step Built-in DIFF amplifier inputs, ideal for external input Built-in volume circuit for mixing external signal available with changing by 1dB/Step Package is SSOP-A24. Putting input-terminals together and output-terminals together can make PCB layout easier and can makes area of PCB smaller. 2 It is possible to control by 3.3V for I C-BUS Controller (Note1 : Grade 3) Applications SSOP-A24 Suitable for the Car Audio systems, Car Navigation systems.
