-*Features:
-*Eliminates need for dual supplies
-*Large DC voltage gain = 100dB
-*High bandwidth = 1MHz
-*Low input offset voltage = 2mV
-*Wide supply range = +-1.5V to +-16V
-*
-*NOTE: Model is for single device only and simulated
-* supply current is 1/4 of total device current.
-* Output crossover distortion with dual supplies
-* is not modeled.
