8-bit high-speed analog-to-digital converter
Product specification
TDA8714
FEATURES
• 8-bit resolution
• Sampling rate up to 80 MHz
• No missing codes guaranteed
• High signal-to-noise ratio over a large analog input
frequency range (7.7 effective bits at 4.43 MHz
full-scale input at fclk = 80 MHz)
• Overflow/underflow 3-state TTL output
• TTL compatible digital inputs
• Low-level AC clock input signal allowed
• External reference voltage regulator
• Power dissipation only 340 mW (typical)
• Low analog input capacitance, no buffer amplifier
required
• No sample-and-hold circuit required.
APPLICATIONS
High-speed analog-to-digital conversion for:
• video data digitizing
• radar pulse analysis
• transient signal analysis
• high energy physics research
• Σ∆ modulators
• medical imaging.
GENERAL DESCRIPTION
The TDA8714 is an 8-bit high-speed Analog-to-Digital
Converter (ADC) for professional video and other
applications. It converts the analog input signal into 8-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.
