DRIVE CIRCUIT AND DRIVING DEVICE INCLUDING THE SAME

PURPOSE: An operating circuit and an operating device with the same are provided to have a plurality of current channels and control an input control current while a channel operating unit is shared, thereby providing a plurality of different operating currents. CONSTITUTION: A channel operating unit(100) generates a first operating current. The channel operating unit provides a channel operating voltage based on a first operating current and a bias voltage. A current channel unit(200) uses the channel operating voltage and the bias voltage. The current channel unit provides a second operating current which is linear about the first operating current. The channel operating unit includes a first operating current generating, a first stabilizer, and a channel operating device.
