Lac503p Schematic -

: Car audio units contain electrostatic-sensitive devices (ESD). Use antistatic wrist straps to prevent damaging the logic board.

The schematic begins at pins 2 and 3 (IN_A, IN_B). The internal multiplexer is controlled by the logic states of SEL_0 and SEL_1 (Pins 7 & 8). This allows the chip to sample multiple sensor inputs or audio lines. The selected signal is routed to the internal amplifier. lac503p schematic
