GENERAL DESCRIPTION
The AD7366 is a dual, 12-bit, high speed, low power, successive approximation ADC that features throughput rates up to 1 MSPS. The device contains two ADCs, each preceded by a 2channel multiplexer, and a low noise, wide bandwidth trackand-hold amplifier that can handle input frequencies in excess of 10 MHz. The AD7366 is fabricated on Analog Devices’ Industrial CMOS process, iCMOS, a technology platform combining the advantages of low and high voltage CMOS, bipolar and high voltage DMOS processes. The process allows the AD7366 to accept high voltage bipolar signals in additio...
