NXP Semiconductors TDA9964
The TDA9964 is a 12-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, PGA, clamp loops and a low-power 12-bit ADC together with its reference voltage regulator. The PGA gain and the ADC input clamp level are controlled via the serial interface.FEATURES
