PIN FUNCTIONS VEE (Pins 1, 2):
Negative Supply Voltage. VEE pins are not
EN (Pin 11):
Enable Control Pin. An internal pull-up resis- internally connected to each other and must all be con- tor of 46k will turn the part off if the pin is allowed to fl oat nected externally. Proper supply bypassing is necessary and defi nes the pin’s impedance. When the pin is pulled for best performance. See the Applications Information low, the part is enabled. section.
