ML6411

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.

DC Supply Voltage (AVCC, DVCC, VCCO) .... -0.3V to 7V
Analog & Digital Inputs/Outputs ........ -0.3 to AVCC+0.3V
Input Current Per Pin .............................. -25mA to 25mA
Storage Temperature Range...................... 65°C to 150°C

The ML6411 is a Dual Video A/D converter, incorporating two input sample and holds, two high speed 8-Bit A/D converters, programmable gain control, selectable clamps, multi-phase clocking, and reference voltage generation. The ML6411 can be used to convert the following analog signals to digital signals: two composite channels or Svideo channel.

All inputs of ML6411 are provided with appropriate input selectable clamps to establish DC level. The clamps are full DC restore circuits with the A-to-D converters in each respective correction loop. The clamps of ML6411 are selectable to 16, 24, 64, and 128. The programmable gain control provides various possibilities to select and adjust the gain via two separate mechanisms: Sync-Suppressed Gain Control (SGC) for sync suppressed video such as RGB, and User Gain Control (UGC) for video formats that require scalable gain settings. Each of these ML6411 can be programmed through a serial bus.
