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.
