General Description
The APA2037 is a stereo, fully differential Class-AB audio
amplifier which can operate with supply voltage from 2.4V
to 5V and is available in a TQFN5x5-20A package.
The built-in feedback resistors can minimize the external
component counts and save the PCB space. High PSRR
and fully differential architecture increase immunity to
noise and RF rectification. In addition to these features, a
short startup time and small package size make the
APA2037 is an ideal choice for LCD TVs and notebook
PCs and Portable devices.
The APA2037 also integrates the de-pop circuitry that re-
duces the pops and click noises during power on/off and
shutdown mode operation. Both Thermal and over-cur-
rent protections are integrated to avoid the IC to be de-
stroyed by over temperature and short-circuit.
The APA2037 is capable of driving 3W at 5V into 3Ω
speaker.
