Crocus Technology recommends following a 4-layer PCB stackup with a solid ground plane, using 1 oz copper thickness, and keeping the signal traces as short as possible. Additionally, decoupling capacitors should be placed close to the device pins, and the power supply should be filtered to minimize noise.
The CT425-HSN820MR has a thermal pad on the bottom of the package, which should be connected to a thermal ground plane on the PCB. The device can operate up to 125°C junction temperature, but thermal design considerations should be made to keep the junction temperature below 100°C for optimal performance and reliability.
The recommended operating voltage range for the CT425-HSN820MR is 3.3V ± 10%. Operating outside this range may affect the device's performance, including reduced sensitivity, increased noise, and decreased accuracy.
The CT425-HSN820MR has built-in EMI filters and is designed to meet EMC standards. However, proper PCB design and layout, including shielding and grounding, are still necessary to ensure optimal EMI and EMC performance.
The typical current consumption of the CT425-HSN820MR is around 10mA at 3.3V supply voltage. The current consumption increases with operating frequency, but the exact variation depends on the specific application and operating conditions.
