The recommended power-up sequence is to apply VCC first, followed by VEE, and then the analog and digital inputs. This ensures proper device operation and prevents latch-up.
To minimize noise and ensure proper operation, keep analog and digital traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Also, avoid running digital traces near analog inputs.
The maximum allowable input voltage is ±10V, exceeding which may cause device damage. Ensure that input signals are properly attenuated or clamped to prevent overvoltage.
Use ESD protection devices, such as TVS diodes or ESD arrays, on the input lines to protect the PCM54HP from electrostatic discharge. Follow proper PCB design and handling practices to minimize ESD risks.
The PCM54HP has a thermal derating of 5.5 mW/°C above 25°C. Ensure proper heat sinking and thermal management to prevent overheating and device failure.
