ad7366/ad7367真双极性输入双12位/14位双通道同时采样SAR ADC

　　The AD7366/AD73671 The AD7366/AD7367 are fabricated on the Analog Devices， Inc.， industrial CMOS process （iCMOS are dual 12-bit/14-bit， high speed， low power， successive approximation analog-to-digital converters （ADCs） that feature throughput rates up to 1 MSPS. The device contains two ADCs， each preceded by a 2-channel multiplexer， and a low noise， wide bandwidth track-and-hold amplifier. 2 The AD7366/AD7367 have an on-chip 2.5 V reference that can be disabled to allow the use of an external reference. If a 3 V reference is applied to the DCAPA andDCAPB pins， the AD7366/AD7367 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDD and VSS supplies are required for the ±12 V input range. ）， which is a technology platform combining the advantages of low and high voltage CMOS. The iCMOS process allows the AD7366/AD7367 to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366/AD7367 can accept true bipolar analog input signals in the ±10 V range， ±5 V range， and 0 V to 10 V range.
