NOT RECOMMENDED FOR NEW DESIGN USE PAM8013 or PAM8304 PAM8301 FILTERLESS CLASS-D MONO AUDIO AMPLIFIER Description Pin Assignments The PAM8301 is a 1.5W Class-D mono audio amplifier. Its low THD+N feature offers high quality sound reproduction. The new filterless architecture allows the device to drive speaker directly instead of using low-pass output filters, therefore saving 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. Features Applications 1.5W Output at 10% THD with a 8 Load and 5V Power Supply PMP/MP4 Filterless, Low Quiescent Current and Low EMI GPS High Efficiency up to 88% Portable Speakers Superior Low Noise Walkie Talkie Short Circuit Protection Handsfree Phones/Speaker Phones Thermal Shutdown Cellular Phones Few External Components to Save Space and Cost Tiny SOT23-6 Package Pb-Free Package Typical Applications Circuit 1 of 10 September 2020 PAM8301 Diodes Incorporated www.diodes.com Document number: DS36431 Rev. 2 - 3 PAM8301 Pin Descriptions Pin Pin Function Number Name Negative Output 1 OUT- 2 GND Ground 3 IN Input 4 SD Shutdown, Active Low 5 VDD Power Supply Positive Output 6 OUT+ Functional Block Diagram Absolute Maximum Ratings ( T = +25C, unless otherwise specified.)
