... V- supply to prevent unwanted current flow to the thermal pad. Do not tie this pin to GND as this could result in large back biased currents flowing between GND and V-. The EL4342 uses the package with pad dimensions 2.48mm and E2 = 3.4mm. Maximum AC performance is achieved if the thermal pad is attached to a dedicated de-coupled layer in a multi-layered PC board ...
