General description

The ADC0806030/040/050 are a family of 8-bit high-speed, low-power Analog-to-Digital Converters (ADC) for professional video and other applications. It converts the analog input signal into 8-bit binary coded digital signals at a maximum sampling rate of 50 MHz. All digital inputs and outputs are Transistor-Transistor Logic (TTL) and CMOS compatible, although a low-level sine wave clock input signal can also be used.
