描述 Description

The HI-7153 is an 8 channel high speed 10 bit A/D converter which uses a Two Step Flash algorithm to achieve through-put rates of 200kHz. The converter features an 8 channel CMOS analog multiplexer with random channel addressing. A unique switched capacitor technique allows a new input voltage to be sampled while a conversion is taking place.
