- Higher SNR than AD7091R-5BRUZ (vs AD7091R-5BRUZ)
Design Notes
Ensure a clean and stable power supply for the AD4005BRUZ. Use a low-dropout regulator (LDO) to provide 5V to the VDD pin, and place 0.1uF and 10uF decoupling capacitors close to the VDD and VIO pins. The reference voltage should be decoupled with a 10uF capacitor to minimize noise.
For optimal performance, use a solid ground plane and separate analog and digital ground areas. Keep the analog input traces short and shielded to reduce noise pickup. Place the ADC close to the signal source to minimize trace inductance. Use differential routing for the IN+ and IN- inputs to maintain common-mode rejection.
Avoid driving the analog inputs beyond the specified common-mode range, as this can cause incorrect conversions. Ensure the SPI clock frequency does not exceed the maximum specified in the datasheet. Also, do not leave the PD pin floating; tie it to a defined logic level to prevent unintended power-down.
