APPLICATION NOTES:

Application Note 1 - Parasitic Diode in Precharge Circuit:

The MX823 has a parasitic diode connected between the precharge reference pin PRECHA and column outputs

1, 4, … , 238, and between PRECHB and outputs 2, 5, … , 239, and between PRECHC and outputs 3, 6, …,

240 as shown below. This means that the precharge voltage must be set above the display diode anode volt-

ages during calibration and at or above display diode anode voltages during operation or output current will flow

through the parasitic diodes and not the display.
