GENERAL DESCRIPTION\nThe TDA8705A is a 6-bit high-speed dual analog-to-digital converter (ADC) for satellite video and other applications. It converts the two analog input signals into two 6-bit binary-coded digital words at a maximum sampling rate of 80 MHz. All digital inputs and outputs are TTL compatible, although a low-level sine wave clock input signal is allowed.FEATURES\n? 2 times 6-bit resolution\n? Sampling rate up to 80 MHz\n?
