VP1058
8-BIT, 25MHz, VIDEO FLASH ADC (SINGLE + 5V SUPPLY)
DS3003 - 3.0
The VP1058 is a low power analog-to-digital flash
converter which requires no preceding sample and hold
stage. Operating from a single +5V supply, it is capable of
digitising analog signals with frequencies up to the Nyquist
limit.
Output data is available in four possible 8-bit formats,
selectable via two digital control inputs, giving either true or
inverted code in binary or offset twos' complement.
