Ai4402
Signal Processor for CCD Monochrome Camera
Description
The Ai4402 is designed to perform the
basic signal processing in CCD
monochrome camera
through a single chip. This bipolar IC is
most suitable for compact usage and low
power consumption.
Feature
• Processing from CCD output to 75¥ Øvideo
output with a single chip
• Wide variable AGC (1 to 32 dB Typ.)
• Built-in operational amplifier for AGC loop
• 75¥ Øline capacitance minimized using sag
compensation function
• Variable white clip level realize wide
dynamic range (140 IRE)
• 32pin TQFP
