A good PCB layout for the LMC6035IMMX/NOPB involves separating the analog and digital grounds, using a solid ground plane, and keeping the input and output traces short and away from each other. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure the LMC6035IMMX/NOPB is operating within its recommended operating conditions, make sure the supply voltage is within the range of 2.7V to 5.5V, the operating temperature is within the range of -40°C to 125°C, and the input voltage is within the range of VCC-1.5V to VCC+0.5V.
The recommended capacitor value for the bypass capacitor connected to the VCC pin is 0.1uF to 1uF, with a voltage rating of at least 6.3V. A ceramic capacitor with a low ESR (Equivalent Series Resistance) is recommended.
To reduce noise and oscillations in the output of the LMC6035IMMX/NOPB, use a low-pass filter at the output, ensure the input is properly filtered and decoupled, and use a stable and low-noise power supply. Additionally, minimize the length of the output traces and use a shielded cable if the output is connected to a remote load.
The recommended method for thermal management of the LMC6035IMMX/NOPB is to use a heat sink or a thermal pad on the exposed pad of the package, and to ensure good airflow around the device. The thermal pad should be connected to a solid ground plane to ensure good heat dissipation.
