6-bit high-speed dual Analog-to-Digital Converter (ADC)
FEATURES 2 times 6-bit resolution Sampling rate up to 80 MHz High signal-to-noise ratio over a large analog input frequency range (5.5 effective bits at 20 MHz full-scale input at fclk = 80 MHz) TTL output Two separated inputs (AC-coupling) TTL compatible digital inputs Low-level AC clock input signal allowed Internal reference voltage
regulator (external reference regulation possible) Power dissipation only 250 mW (typical) Low analog input capacitance, no buffer amplifier required No sample-and-hold circuit required. QUICK REFERENCE DATA SYMBOL VCCA VCCD VCCO ICCA ICCD ICCO ILE DLE AILE fclk(max) Ptot Note 1. Full-scale sine wave (fi = 20 MHz; fclk = 80 MHz).
