Philips Semiconductors
8-bit high-speed analog-to-digital converter
Product specification
TDA8718
FEATURES
• 8-bit resolution
• Sampling rate up to 600 MHz
• ECL (100K family) compatible for digital inputs and
outputs
• Overflow/Underflow output
• 50 Ω load drive capability
• Low input capacitance (5 pF typ.).
GENERAL DESCRIPTION
The TDA8718 is an 8-bit analog-to-digital converter (ADC)
designed for professional applications. The device
converts the analog input signal into 8-bit binary coded
digital words at a sampling rate of 600 MHz. It has an
effective bandwidth capability up to 150 MHz full-scale
sine wave. All digital outputs are ECL compatible.
APPLICATIONS
• High speed analog-to-digital conversion
• Industrial instrumentation
• Data communication
• RF communication.
QUICK REFERENCE DATA
Measured over full voltage and temperature ranges, unless otherwise specified.
