Overview
The AD7366BRUZ-5500RL7, produced by Analog Devices Inc., is a dual 12-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC). This device features two ADCs, each preceded by a 2-channel multiplexer and a low noise, wide bandwidth track-and-hold amplifier. Fabricated on Analog Devices' industrial CMOS (iCMOS) process, it combines the advantages of low and high voltage CMOS, enabling the acceptance of true bipolar analog input signals and reducing power consumption and package size.
