PAM8301

PAM8301 Filterless Class-D Mono Audio Amplifier Key Features www.datasheet4u.com and 5V General Description The PAM8301 is a 1.5W class-D mono audio amplifier. Its low THD+N feature offers highquality sound reproduction. The new filterless architecture allows the device to drive speaker directly instead of using low-pass output filters, therefore save system cost and PCB area. With the same number of external components, the efficiency of the PAM8301 is much better than that of class-AB cousins. It can optimize battery life thus is ideal for portable applications. The PAM8301 is available in SOT23-6 package. n 1.5W Output at 10% THD with a 8 Ω Load Power Supply n Filterless, Low Quiescent Current and Low EMI n High Efficiency up to 88% n Superior Low Noise n Short Circuit Protection n Thermal Shutdown n Few External Components to Save Space and Cost n Tiny SOT23-6 Package n Pb-Free Package Applications n n n n n n PMP/MP4 GPS Portable Speakers Walkie Talkie Handsfree phones/Speaker Phones Cellular Phones Typical Application VDD 10μF 5 VDD 3 Audio 0.1μF IN 1μF OUT+ 6 PAM8301 Shutdown 4 /SD GND 2 OUT- 1 Power Analog Microelectronics , Inc www.poweranalog.com 1 09/2008 Rev 1.2 PAM8301 Filterless Class-D Mono Audio Amplifier Block Diagram VDD www.datasheet4u.com VDD/2 + IN RI RF DRIVER MODULATOR +OUT -OUT THERMAL PROTECTION SD SHUTDOWN INTERNAL OSCILLATOR CURRENT PROTECTION OSC GND Pin Configuration & Marking Information TOP VIEW SOT23-6 6 5 4 FPXYW ...
