EUA6288

EUA6288 14VP-P, Mono, Class G Ceramic Speaker Driver DESCRIPTION The EUA6288 is a mono Class G power amplifier with an integrated inverting charge-pump power supply. The charge pump can supply up to 500mA of peak out-put current over at 5V, guaranteeing an output of 14VP-P. The EUA6288 offers good performance through the class G output stage, which provides efficiency levels greater than Class AB devices without the EMI penalties commonly associated with Class D amplifiers. The EUA6288 is ideally designed to deliver the high output voltage swing for ceramic/piezoelectric speakers. The device utilizes fully differential inputs and outputs, comprehensive click-and-pop suppression, shutdown control, and soft-start circuitry. The EUA6288 is available in 28-pin TQFN (4mm × 4mm) package.
