Small-sized Class-D Speaker Amplifiers Analog Input Monaural Class-D Speaker Amplifiers BD5632NUX,BD5634NUX,BD5638NUX ● 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 BD5632NUX BD5634NUX BD5638NUX Gain (dB) 6 12 18 Input Impedance (kΩ) 100 50 25 Package VSON008X2030 ● Absolute maximum ratings (Ta=25℃) Parameter Symbol Ratings Unit Power Supply Voltage VDD 7.0 V Power Dissipation Pd 0.52 *1 W Storage Temperature Range Tstg -55 ~ +150 ℃ STBY Terminal Input Range Vstby -0.3 ~ VDD+0.3 V IN+, IN- Terminal Input Range Vin -0.3 ~ VDD+0.3 V (*1) ROHM standard board mounted (Board size 70mm×70mm×1.6mmt, 1layer), de-rate the value 4.16mW/deg above Ta=+25deg. ● Operating conditions Parameter Symbol Ratings Unit Power Supply Voltage VDD +2.5 ~ +5.5 V Temperature Range Topr -40 ~ +85 ℃ *This product is not designed for protection against radioactive rays.
