2.4W, Mono Class G
Audio Power Amplifier with AGC
DESCRIPTION
The EUA6230 is a mono Class G power amplifier with an
integrated inverting charge-pump power supply and
automatic gain control (AGC). The charge pump can
supply up to 500mA of peak out-put current over a 2.7V to
5V supply voltage range, guaranteeing up to 2.4W output
power into an 8Ω load. The AGC function can prevent
distortion of the audio signal by detecting output signal
clip due to the over level input signal and compressing it
automatically.
The EUA6230 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 device
utilizes fully differential inputs and outputs, comprehensive
click-and-pop suppression, shutdown control, and soft-start
circuitry. The EUA6230 is available in 28-pin TQFN
(4mm× 4mm) package.
