GENERAL DESCRIPTION
The TDA9965 is a 12-bit analog-to-digital interface for a
CCD camera. The device includes a CTH circuit, PGA and
a low-power 12-bit ADC, together with its reference
voltage regulator.
The CTH has a bandwidth circuit controlled by on-chip
DACs via a serial interface.
A 10-bit digital clamp controls the ADC input clamp level.
