- SINAD > 90 dBFS (vs AD4008BCPZ)
- Easy Drive technology (vs AD4008BCPZ)
Design Notes
Ensure clean power supply for the AD4080BCPZ. Use low-noise LDO regulators and place decoupling capacitors close to the VDD pin. The integrated decoupling capacitors reduce external requirements, but additional 0.1uF and 10uF capacitors are recommended for optimal performance.
Follow the layout guidelines in the AD4080 datasheet. Keep the analog input traces short and shielded to minimize noise pickup. Use a solid ground plane and separate analog and digital grounds to reduce interference. The LFCSP package requires proper thermal pad soldering for heat dissipation.
Avoid exceeding the absolute maximum ratings for supply voltage and input voltage. Ensure the reference voltage is stable and well-decoupled. The Easy Drive input reduces input-dependent currents, but still use appropriate driver amplifiers to maintain signal integrity at high frequencies.
