12-Bit ADC Circuit Design


design for me a block diagram that will aid me in designing a 12 bit ADC circuit. Components are ; 12-bit ADC IC ADS1115, Reference voltage source that is stable of 3.3v, analogue signal source from a 4 bit multiplexer, an stm32 or ESP32 MCU to process the digital output, RC filter to reduce noise on the input signal. power supply. design for me the block diagram to aid for wiring diagram
Below is a block diagram in Mermaid code to help you plan the wiring of your 12‑bit ADC circuit:
