CXA1390AQ/AR
S/H and AGC for CCD Camera
Description
CXA1390AQ
CXA1390AR
The CXA1390AQ/AR are CCD camera's signal
processing ICs which extract signals from the CCD
output. These bipolar ICs perform correlated double
sampling. AGC, color separation, high luminance
detection and others. Additionary, these ICs are not
affected by irregular pulses which occure during the
CCD shutter mode.
48 pin QFP (Plastic)
48 pin LQFP (Plastic)
Featuers
• Pin compatible upgraded version of CXA1390Q/R
which can be swapped out while using same
peripheral chips
• Almost completely corrects irregular pulses and
their negative affects
Application
S/H and AGC for CCD camera
• Correlated double sampling function alllows for the
suppression of low band noise in the CCD output
• AGC amplifier, which has High S/N ratio and wide
gain control range, enhances the camera sensitivity
• Output for iris adjustment. High luminance
detection output
• Usage of Vg (regulator) output allows for the
formation of IRIS and AGC LOOP which are not
affected by supply voltage functation
