Notes
1. Only for pins 6 and 8 when clamp action is not selected for these pins.
2. On all the video input pins, when non-I2C-bus control mode is selected or when clamp action is selected on
pins 6 and 8 (by I2C-bus control).
3. Connected between VCC and pin 4 or pin 15.
4. Connected between AGND and pin 4 or pin 15.
CHARACTERISTICS
VCC = 8 V; Tamb = 25 °C; gain condition, clamp condition and OFF state are controlled by the I2C-bus;
unless otherwise specified.
