The AD7367-5 are dual, 14-bit, low power, successive approximation analog-to-digital converters (ADCs) that feature throughput rates up to 500 kSPS. Each device contains two ADCs, which are both preceded by a 2-channel multiplexer, and a low noise, wide bandwidth, track-and-hold amplifier.

The AD7367-5 are fabricated on the Analog Devices, Inc., industrial CMOS process (iCMOS^®), which is a technology platform combining the advantages of low and high voltage CMOS. The process allows the parts to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7367-5 can accept true bipolar analog input signals in the ±10 V range, ±5 V range, and 0 V to +10 V range.

The devices 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 and DCAPB pins, the AD7367-5 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.
