8
A control pin to control on/off lamp. This input enable the
inverter operation (Lamp On) when high and disables the inverter
when low. This signal is output from a 3.3V CMOS device.
Max loading = 100uA
Logic Low = 0.8 volts Max.
Logic High =1.8 volts Min.
12
This signal is an open collector sink signal to drive LED1. The
LED current is limited by a series resistor of 1KΩ.
13
This signal is an open collector sink signal to drive LED2. The
LED current is limited by a series resistor of 1KΩ.
14
This a 5 volt supply for powering the LEDs. It should not be used
for any other purpose.
18
This is a 5 volt power line for the analog circuits and display
LEDs on the inverter board.
19, 20
This is the return ground for the microphone circuit. It should not
be connected to VGND or other circuit on the inverter board.
21
This is the output of the microphone preamplifier circuit.
