A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between the VCC and GND pins to filter out noise.
Use a high-quality, low-noise power supply with a voltage regulator to ensure a stable 3.3V supply. Decouple the power pins with 10uF and 100nF capacitors in parallel to filter out noise and ripple.
The ADA-4643-BLKG supports clock frequencies up to 100 MHz. However, the maximum frequency may vary depending on the specific application and PCB layout.
Configure the ADA-4643-BLKG in differential mode for optimal analog-to-digital conversion. Use a high-impedance source and a low-pass filter to reduce noise and aliasing. Adjust the gain and offset settings based on the specific application requirements.
The recommended operating temperature range for the ADA-4643-BLKG is -40°C to 85°C. However, the device can operate up to 125°C with reduced performance and reliability.
