GENERAL DESCRIPTION
The TDF8704T is an 8-bit high-speed analog-to-digital converter (ADC) for general industrial applications. It converts the analog input signal into 8-bit binary-coded digital words at a maximum sampling rate of 50 MHz. All digital inputs and outputs are TTL compatible, although a low-level AC clock input signal is allowed.
FEATURES
• 8-bit resolution
• Sampling rate up to 50 MHz
• Extended temperature range (−40 to +85°C)
• High signal-to-noise ratio over a large analog input frequency range (7.4 effective bits at 4.43 MHz full-scale input and at fclk= 50 MHz)
• Binary 3-state TTL outputs
• Overflow/underflow 3-state TTL output
• TTL compatible digital inputs
• Low-level AC clock input signal allowed
• Stable internal reference voltage regulator included
• Power dissipation only 380 mW (typical)
• Low analog input capacitance, no buffer amplifier required
• No sample-and-hold circuit required.
