Instructions for AD7871JP

1. Power Supply Connection:

   • Connect the VDD pin to a power supply within the operating voltage range of 4.75V to 5.25V.
   • Ensure proper decoupling capacitors are placed close to the power pins.

2. Reference Voltage Setup:

   • The internal reference voltage is typically set to 2.5V, but it can vary slightly between 2.4V and 2.6V.
   • For higher accuracy, an external reference can be used by connecting it to the VREF pin.

3. Analog Input Configuration:

   • Analog inputs should not exceed the reference voltage (VREF) and must be within the range of 0V to VREF.
   • Use appropriate input protection circuits if signals may exceed these limits.

4. Conversion Timing:

   • Maximum conversion time is 13 渭s. Ensure that the system allows sufficient time for conversions to complete before reading data.

5. Temperature Considerations:

   • Operate the device within the temperature range of -40掳C to +85掳C for optimal performance.
   • Store the device in environments where temperatures do not drop below -65掳C or rise above +150掳C.

6. Power Dissipation:

   • Keep power dissipation below 180 mW to avoid overheating and ensure reliable operation.

7. Reading Data:

   • Follow the specific protocol or interface method (SPI, I2C, etc.) as defined in the datasheet for data communication with the AD7871JP.
