ADI AD7366BRUZ

The AD7366/AD7367 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. The AD7366/AD7367 are fabricated on the industrial CMOS process (iCMOS), 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. 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 D_CAPA and D_CAPB pins, the AD7366/AD7367 can accept a true bipolar ±12 V analog input. Minimum ±12 V V_DD and V_ss supplies are required for the ±12 V input range.
