|
*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 1/2 of total device current.
|
|
* Output crossover distortion with dual supplies
|
|
* is not modeled.
