ORDERING INFORMATION TYPE NUMBER TDA9962HL PACKAGE NAME LQFP48 DESCRIPTION plastic low profile quad flat package; 48 leads; body 7 × 7 × 1.4 mm APPLICATIONS TDA9962 Low-power, low-voltage CCD camera systems. GENERAL DESCRIPTION The TDA9962 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. An additional DAC is...
