LA47202P Product details

Description

of Operation 1. Standby switch function (pin 4) The pin 4 threshold voltage is set to about 3 VBE.The amplifier is turned ON at the application voltage of 3.0V or more and OFF at 0.5V or less.2. Muting function (pin 22) When pin 22 is set to the ground potential, the LA47202P goes to the muted state.This supports implementation of an audio muting function.The muting function is turned on when a level of 1V or lower is applied through a 10kΩ resistor, and the function is turned off when this
