Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines for signal traces.
To ensure accurate voltage measurement, it's essential to follow proper layout and routing guidelines, use a low-impedance voltage source, and minimize noise coupling. Additionally, consider using a voltage reference IC, such as the REF5025, to provide a stable voltage reference.
The LHV870LC is specified to operate from -40°C to 125°C, but it's essential to consider the operating temperature range of the specific application and ensure that the device is properly derated for temperature.
The LHV870LC has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Additionally, consider using ESD protection devices, such as TVS diodes, to protect the device from external ESD events.
The recommended power-up sequence for the LHV870LC is to power up the VCC supply first, followed by the VIN supply. This ensures that the internal voltage regulators are properly initialized and that the device operates correctly.
