Instructions for Using MCP3204-BI/P

1. Power Supply:

   • Connect the VDD pin to a stable power supply within the range of 2.7V to 5.5V.
   • Connect the VSS pin to ground.

2. Reference Voltage:

   • Connect the VREF pin to a stable reference voltage within the range of 2.7V to 5.5V. If not used, connect it to VDD for a full-scale input range.

3. Analog Inputs:

   • Connect the analog signals to be measured to the AN0, AN1, AN2, and AN3 pins. Ensure the input voltage is within the range of 0V to VREF.

4. Digital Interface:

   • Connect the CS (Chip Select), SCK (Serial Clock), DIN (Data In), and DOUT (Data Out) pins to your microcontroller or digital interface.
   • Set CS low to initiate communication.
   • Use the SCK line to clock data into and out of the ADC.
   • Data is shifted out on the rising edge of SCK and sampled on the falling edge.

5. Conversion Start:

   • Send a start conversion command by setting CS low and sending the appropriate control word via DIN.
   • The control word specifies the channel to be converted and the mode of operation (single-ended or differential).

6. Data Read:

   • After the conversion is complete, the data can be read from the DOUT pin.
   • The conversion result is 12 bits long and is transmitted in MSB-first format.

7. Power-down Mode:

   • To enter power-down mode, set CS high and keep it high until the next conversion is needed.
   • This reduces power consumption to approximately 0.5 渭A.

8. Temperature Considerations:

   • Ensure the operating temperature is within the specified range of -40掳C to 85掳C to maintain accuracy and reliability.

9. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store in a dry, cool place away from direct sunlight and sources of heat.
