![]() ![]() The maximum current for each segment pin is 100mA and for each DIGIT ground pin is 500mA.MAX7219 works well in a temperature range of 0☌ to +70☌.The data is displayed on segments with a delay time of 2.2ms.It provides a feature of digital and analog brightness intensity control and a 150♚ shutdown mode in which the current of all segments is pulled to ground.Normally, the voltage supply of +5V is used. Its operation is specified in a voltage range of +4.0 to +5.5V.It is an LED driver display IC with a 10MHz serial interface which allows the user to select the decode/No-Decode digit.It is the terminal for a positive power supply. ![]() This resistor is used to adjust the value of the current. This pin is used to set the output current by connecting a resistor at this pin whose other terminal is connected to the ground. ![]()
