General Description
The PAM8012 is a 2.0W mono filterless class-D
amplifier with high PSRR and differential input that
reduce noise.
Features like 90% efficiency and small PCB area
make the PAM8012 Class-D amplifier ideal for
cellular handsets. The filterless architecture
requires no external output filter, fewer external
components, less PCB area and lower system
costs, and simplifies application design.
The PAM8012 features anti-saturation function
which detect output signal clip due to the over
input level and keep the output non-saturation
automatically to get the excellent sound quality.
The maximum output power without clip can be set
by one resistor at PL pin that to prevent the
speaker to be damaged..
The PAM8012 features short circuit protection and
over temperature protection.
The PAM8012 is available in tiny WCSP9 (1.3mm
x 1.3mm) and eMSOP10 packages.
