1 IN Input. Connect this pin to the CCD sensor output. 2 VEE Negative Power Supply Voltage. 3 OUT Output. Connect this pin to the AFE input. 4 IDRV Bandwidth Adjustment Pin. Connect this pin to VCC or an external voltage with an external resistor. This pin allows bandwidth to be controlled by adjusting ICC. This pin can also be used to power down the buffer. 5 VCC Positive Power Supply Voltage. 6 ISF Active Load Current Adjustment Pin. Connect to VCC or an external voltage with an external resistor. This pin can also be connected to the microcontroller logic output through an external resistor for power save mode. This pin can also be used to power down the active current load.
