AD7865YSZ-1

AD7865 is a fast, low power, four-channel simultaneous sampling 14-bit A/D converter that operates from a single 5V supply. A single conversion start signal (CONVST) simultaneously places all the track/holds into hold and initiates conversion sequence for the selected channels. The EOC signal indicates the end of each individual conversion in the selected conversion sequence. The BUSY signal indicates the end of the conversion sequence. The part allows any subset of the four channels to be converted in order to maximize the throughput rate on the selected sequence. The channels to be converted can be selected either via hardware (channel select input pins) or via software (programming the channel select register). It is widely used in application such as AC motor control, uninterruptible power supplies, industrial power meters/monitors, data acquisition systems, communications etc.
