- Easy Drive technology (vs AD4683BCPZ)
Design Notes
The AD4698BCPZ operates from an analog supply of 3.15 V to 5.5 V. Ensure that the AVDD and DVDD pins are properly decoupled with 0.1 uF and 10 uF capacitors placed close to the pins. The reference voltage (VREF) should be stable and noise-free; use a low-noise reference such as the ADR4520 for optimal performance.
For best performance, place the AD4698BCPZ on a PCB with a solid ground plane. Keep analog and digital grounds separate and connect them at a single point. Route analog input traces away from digital signals to minimize crosstalk. Use short, direct traces for the SPI interface to reduce parasitic capacitance.
Avoid driving the analog inputs beyond the supply rails, as this can cause latch-up or damage. The Easy Drive feature reduces input current, but still ensure the source impedance is within the specified range. Do not leave unused inputs floating; tie them to GND or AVDD as appropriate. Also, ensure the SPI bus is properly terminated to avoid signal integrity issues.
