Common Output 2/LCD Segment Output 28. COM2 is used for the LCD backplane.
In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or
an analog output when the LCD charge pump is enabled. In the ADE7116/ADE7156, this pin is always an
analog input. When this pin is an analog output, it should be decoupled with a 470 nF capacitor. When this
pin is an analog input, it is internally connected to V
LCDVB to generate the two highest voltages for the LCD waveforms (see the LCD Driver section).
In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or
an analog output when the LCD charge pump is enabled. In the ADE7116 and ADE7156, this pin is always an
analog input. When this pin is an analog output, a 100 nF capacitor should be connected between this pin and
LCDVP1. When this pin is an analog input, it is internally connected to LCDVP1 (see the LCD Driver section).
In the ADE7166/ADE7169, this pin can be either an analog input when the LCD resistor driver is enabled or
an analog output when the LCD charge pump is enabled. In the ADE7116/ADE7156, this pin is always an
analog input. When this pin is an analog output, it should be decoupled with a 470 nF capacitor. When this
pin is an analog input, a resistor should be connected between this pin and LCDVC to generate an
intermediate voltage for the LCD driver. In 1/3 bias LCD mode, another resistor must be connected between
this pin and LCDVA to generate another intermediate voltage. In 1/2 bias LCD mode, LCDVB and LCDVA are
internally connected (see the LCD Driver section).
