设计说明
Provide a clean analog supply (AVDD) with low noise and ripple. Use a low-dropout regulator (LDO) to generate 5V from a higher rail, and place 10uF and 0.1uF decoupling capacitors close to the AVDD pins. The digital supply (DVDD) can be derived from the same 5V or a separate 3.3V rail, but ensure proper decoupling with 0.1uF capacitors. The reference input (REF) should be driven by a low-impedance source, such as a precision reference like the ADR421, and bypassed with a 10uF capacitor to REFGND.
For optimal performance, use a 4-layer PCB with dedicated ground and power planes. Place the ADC close to the signal source to minimize trace length and reduce noise pickup. Route analog and digital signals separately, and avoid crossing them. The exposed pad (EP) should be soldered to the ground plane to provide a low thermal resistance path and improve heat dissipation. Use a solid ground plane under the ADC and connect AGND and DGND at a single point to avoid ground loops.
Do not exceed the absolute maximum ratings for AVDD and DVDD. Ensure the input signal is within the selected input range to avoid damage. The REF pin must not be left floating; always connect a reference voltage. The SPI interface should be operated at the correct voltage levels; if the host microcontroller uses 3.3V logic, ensure DVDD is set to 3.3V or use level shifters. Avoid using long wires for SCLK and SDOUT to prevent signal integrity issues. Also, ensure the BUSY signal is monitored to know when the conversion is complete.
