TheTL1051isabipolarmonolithicintegratedcircuitdesignedforuseinpreprocessingthreechannelsofTICCD
image sensors. It receives video inputs from the TI TL1593 three-channel sample-and-hold circuit and outputs
three processed channel signals and a single multiplexed Y (luminance) signal. Processing functions of the
TL1051 include gain, automatic gain control, clamp, white balance, and white clip.
