TDA8783: 10-bit ADC for CCD cameras

The TDA8783 is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC and a low-power 10-bit. Analog-to-Digital Converter (ADC) together with its reference voltage regulator. The AGC and CDS have a bandwidth circuit controlled by on-chip DACs via a serial interface. A 10-bit DAC controls the ADC input clamp level. An additional 8-bit DAC is provided for additional system controls; its output voltage range is 1.4 V (p-p) which is available at pin OFDOUT.

CXA1390: S/H and AGC for CCD Camera

Description:
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.
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
• 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
Application:
S/H and AGC for CCD camera
Structure:
Bipolar silicon monolithic IC
