Small-sized Class-D Speaker Amplifiers Analog Input Monaural Class-D Speaker Amplifiers BD5632NUX,BD5634NUX,BD5638NUX No.10101EAT04 ●Description BD5632NUX, BD5634NUX and BD5638NUX are a low voltage drive class-D speaker amplifier that was developed for mobile phones, mobile audio products and the others. BD5632NUX has a fixed gain of 6dB, BD5634NUX has a fixed gain of 12dB, and BD5638NUX has a fixed gain of 18dB. It is suitable for the application of battery drive because of high efficiency and low power consumption. Also, stand-by current is 0µA (typ.), and fast transitions from standby to active with little pop noise. It is suitable for applications that switch repeatedly between stand-by and active. ●Features 1) LC Filter less 2) Only 3 external components 3) High power 2.5W/4ohm/BTL (VDD=5V, RL=4ohm, THD+N=10%, typ.) 4) High power 0.85W/8ohm/BTL (VDD=3.6V, RL=8ohm, THD+N=10%, typ.) 5) Analog differential input / PWM digital output 6) Pop noise suppression circuit 7) Standby function (Mute function) 8) Protection circuit (Short protection [Auto recover without power cycling], Thermal shutdown, under voltage lockout) 9) Ultra small package VSON008X2030 (2.0×3.0×0.6mmMAX) ●Applications Mobile phones, PND (Personal Navigation Device), DSC, PDA, etc ●Line up matrix Production Name Gain (dB) Input Impedance (kΩ) Package BD5632NUX 6 100 BD5634NUX 12 50 VSON008X2030 BD5638NUX 18 25 ●Absolute maximum ratings (Ta=25℃) Parameter Symbol Ratings Unit Power Supply Voltage...
