The MN6576H is a high-speed 9-bit CMOS analog-todigital converter for image processing applications.
It uses a half flash structure based on chopper comparators and achieves both high speed and low power
consumption with multiplexing.
It provides separate power supply pins for the circuits
driving the low-voltage digital output pins.
