Digital Millivoltmeter PCB Board DIY Kit 5V AD Conversion Welding Soldering Electrical Electronic Skills Teaching Training Suit Deskripsi : Package : TQFP is_customized : Yes Model Number : Digital millivoltmeter Kit Operating Temperature : normal Dissipation Power : low Supply Voltage : 5V Application : Computer Condition : New Type : Logic ICs Brand Name : EC Buying Origin : Mainland China Smart Electronics Experiment : Switch And Sensor For Arduino STM32 This circuit can convert the input analog voltage into a 3-digit half 8421BCD code and display the value through 4 digital tubes. Introduction to working principle MC14433 is a dual-integration A/D converter that converts the input analog voltage into a 3-bit half 8421BCD code. Reference power supply MC1403, providing precision voltage, making reference voltage of A/D converter Seven-segment decoder CD4511 converts 8421BCD code into seven-segment drive signal Display drivers V1 - V4, driving the common end of the three-and-a-half digit digital display. Three-and-a-half-digit display, digitally display the seven-segment signal of the output of the decoder, and read out the A/D conversion result. The three digits refer to the ones, the ten digits, and the hundred digits range from 0-9. The half digits refer to the thousands digits which can only be 0 or 1. They cannot be changed from 0 to 9. So they are called half Happy Shopping.
