VCC0
All VCC, VCCO, and VEE pins must be externally connected to appropriate Power Supply to guarantee proper operation. The thermally
conductive exposed pad on package bottom (see package case drawing) must be attached to a heat-sinking conduit, capable of transfer-
ring 1.2 Watts. This exposed pad is electrically connected to VEE internally.
