GENERAL DESCRIPTION

The ADC-321 is an 8-bit, high speed, monolithic CMOS, sub-ranging A/D converter. The ADC-321 achieves a sampling rate comparable to flash converters by employing a sub-ranging technique which uses multiple comparator blocks each containing a sample-and-hold amplifier. The ADC-321 can operate with either a single +5V or dual +5V and +3.3V power source to allow easy interfacing with 3.3V logic.
