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.

Note 1:All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2:Testing performed with resistive and capacitive loads to simulate an actual ceramic/piezoelectric speaker load,
ZL= 1µF+10Ω.
Note 3:Testing performed with resistive and inductive loads to simulate an actual speaker load. For dynamic speakers,
RL= 8Ω, 68µH.
