General description
The ADC0808S is a differential, high-speed, 8-bit Analog-to-Digital Converter (ADC) optimized for telecommunication transmission control systems and tape drive applications. It allows signal sampling frequencies up to 250 MHz. The ADC0808S clock inputs are selectable between 1.8 V Complementary Metal Oxide Semiconductor (CMOS) or Low-Voltage Differential Signals (LVDS). The data output signal levels are 1.8 V CMOS.
