描述 Description

The HI1176 is an 8-bit, CMOS analog-to-digital converter for video use that features a sync clamp function. The adoption of a 2-step parallel method realizes low power consumption and a maximum conversion speed of 20 MSPS. For higher sampling rates, refer to the pin-for-pin compatible HI1179 data sheet, document number 3666.
