3. I/V conversion
4. AD conversion
Auto Luminous control operates as Low Gain as High Gain at the time of "10" when GAIN (1:0) is "01."
(*1) Please set the relative ratio of resistance. In this case, be careful of the difference in brightness conversion in High Gain mode and Low Gain mode.
・ SBIAS output equips with intermittent operation mode and always ON-mode. Pull-down [ SBIAS and a SSENS terminal ]
・ Detection of Ambient light information is periodically performed for low-power realization.
・ The current which turns off SBIAS and ADC and is generated by the sensor is controlled except the time of Ambient light
Operation mode
Gain switching function is built in to extend the dynamic range.
Effective / non-effect of automatic gain control are register setup.
GC1 and the output logic of GC2 can be set up by the manual
