Design Notes
The AD7387BCPZ operates from a 3.0V to 3.6V supply. Use a low-noise LDO to provide a clean supply voltage. Decouple the VDD and VIO pins with 0.1uF and 10uF capacitors placed close to the pins. The VIO pin should be connected to the same supply as the host interface to ensure proper logic levels.
For optimal performance, place the AD7387BCPZ close to the signal source to minimize trace length and reduce noise pickup. Use a solid ground plane under the device. Route analog inputs away from digital signals to avoid crosstalk. Ensure the reference voltage (VREF) is well-filtered and stable.
Avoid exceeding the absolute maximum ratings for the analog inputs. The input voltage should not exceed VDD + 0.3V or go below -0.3V. Ensure the SPI interface is properly configured for the correct clock polarity and phase. The CS pin must be low during data transfer. Use a series resistor on the SDO line to reduce ringing if the trace is long.
