Incorporated PAM8408 Audio Amplifier offers a highly integrated
solution for low power speakers. Designed as a 2x3 filter-less Class-D
amplifier with memory up/down volume control, PAM8408 delivers high SNR
and differential input to help eliminate noise. PAM8408's filter-less
architecture minimizes the number of external components used and
reduces PCB area. Advanced 32-step up/down volume control also minimizes
external components and enables speaker volume control. The gain will
hold when the chip is in shutdown mode. Built in auto-recovery provides
short circuit protection and thermal shutdown. PAM8408 supports 2.5V to
6V operation, making it suitable for up to four cell alkaline battery
applications. With >87% efficiency and small PCB area, the PAM8408
Class-D amplifier is ideal for portable applications.
