1.9W + 1.9W Stereo Speaker Amplifiers - BD7836EFV

BD7836EFV is a low voltage drive class-AB stereo speaker amplifier, developed for note-book PC, desktop PC, portable devices and others. Class-AB amplifier has no EMI noise. Adopting power package realize high output power. Low shutdown mode electricity reduce consumption of battery. Shutdown current is 0µA typically. BD7836EFV can use for some applications that change mode between "shutdown state" and "active state".

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
