Produk ASLI dari Chipstar Micro-Electronics. Mfr.Part #: CS83501E CS83501E is a built-in BOOST module with anti-sound function Class R audio power amplifier. The design of Class AB and Class D switchable modes minimizes the interference of the power amplifier in the audio subsystem to FM. - Built-in BOOST module R-class structure, integrating two modes of D-class and AB output power Po at 10% THD+N, VIN = 3.7V RL = 2 2+47uH 10.70W(D MODE NCN OFF ) Po at 10% THD+N,VIN = 3.7V RL=32 8.0W(D MODE NCN OFF) Po at 10% THD+N,VIN = 3.7V RL = 4 2 6.30W (D MODE NCN OFF) Excellent #34;pop-noise #34; noise suppression capability Operating voltage range: 2.5V to 5.5V - Built-in fixed gain of 20 times - Advanced power adaptive features - Built-in anti-crack module 75% efficiency - High power supply rejection ratio (PSRR): 70dB at 217Hz - Startup time (240ms) - Quiescent current (10mA) - Low shutdown current
