- 2×21W, 1% THD+N, 14.5V, 4Ω, BTL The ACM3108 is a stereo/mono, Class D audio amplifier Zhisheng Confidential - 1×42W,1%THD+N,14.5V,2Ω,PBTL ï‚Ÿ Excellent Audio Performance - THD+N ≤ 0.02% at 1W, 1kHz, PVDD = 12V - Higher Order Modulator Enable Better THD+N for full audio band - Idle switching A-weighted noise ≤ 63 í µí±¢í µí±¢í µí±¢í µí±¢í µí±…í µí±…í µí±…í µí±…í µí±…í µí±… - <5mV output DC offset ï‚Ÿ Efficient Class-D Operation - >90% efficient Class-D operation eliminates need for heat sink - Low Idle Current: <28mA, PVDD=12V, LC Filter=10uH+0.68uF - Patented Modulation Schemes to Minimize inductor ripple Current for all output power level - Class-H Control improve Efficiency for full output power range ï‚Ÿ Low EMI Technology - Spread Spectrum Option - 180Ëš PWM Phase Shift ï‚Ÿ Gain Management - 20dB, 26dB, 30dB, 34dB fixed gain setting - Mute Operation to stop PWM switching delivers up to 2×21W into 4Ω stereo mode and 1×42W into a 2Ω load in mono mode while offering up to 89% efficiency.
In order to minimize power dissipation, a new patented modulation scheme - Dynamic PWM been used to minimize inductor loss for full output power range.
The ACM3108 operates from a single +4.5V to +14.5V supply, driving the load in BTL or PBTL configuration.
