TDA7265:
The TDA7265 is a 25W+25W stereo sound amplifier with mute/stand-by facility. STPA control signal coming
from microcontroller (when it is at high level) activates the mute function. IC is muted when mute port is at low
level. Two stereo audio signals coming from audio module is injected to the inputs of the IC and a power of
12Wrms (10%) is obtained. An external pop-noise circuitry pulls AF inputs of the IC in order to eliminate pop
noise when TV is turned on or off via mains supply connection. It is possible to adjust the gain of the amplifiers by
feedback external resistors.
