Eutech Microelectronics EUA6230

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.

DESCRIPTION

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.
