Microsemi recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the VCC and VEE supplies. Additionally, keep the input and output traces short and away from each other to minimize noise and crosstalk.
To ensure proper biasing, make sure to follow the recommended voltage and current settings for VCC, VEE, and VREF. Also, ensure that the input common-mode voltage is within the specified range, and that the output load is within the recommended range.
The LE87402MQC is rated for operation from -40°C to +125°C, but it's recommended to operate within the -20°C to +85°C range for optimal performance and reliability.
To prevent ESD damage, use ESD-protective packaging and handling procedures during assembly and testing. Additionally, consider adding external ESD protection devices, such as TVS diodes, to the PCB design.
To prevent latch-up and ensure proper operation, power up the VCC and VEE supplies simultaneously, and then apply the input signals. Ensure that the VREF voltage is stable before applying the input signals.
