Fig.1 Block Diagram of Multiplexer and Level Magnification Circuit
Multiplexer and Level Magnification Circuit of M62255 consists from Reference Voltage, 4times amplifier,
10times Amplifier and 4input Multiplexer.
When setting the reference voltage correspond to detecting voltage by serial data from MCU, this set
voltage supply to reference voltage for A-D converter. The difference between input voltage of IN1 - IN4
and reference voltage is multiplied by 4 at the center of this setting voltage.
This multiplied voltage is supplied to A-D input of MCU from D
OUT
terminal. The resolution of A-D
converter of MCU is improved by 2-Bit as against the difference of IN1-IN4 input.
