TABLE 1. Connectors
This connector is used to control the Shutdown function.
If JU1 is open, then the LM48555 is in Shutdown.
If JU1 is shorted, then the LM48555 is active.
This connector connects the audio input signal to the device
inputs. Apply the positive signal source to the pin labeled “+” and
the negative signal source to the pin labeled “-”.
This connector provides a connection to the amplifier outputs. A
ceramic speaker load, and series resistors, should be connected
across these terminals.
This connector provides the power supply connection. Apply an
external power supply’s positive voltage to the pin labeled V
the ground source to the pin labeled GND.
