Overview
The AD7323BRUZ, produced by Analog Devices Inc., is a 4-channel, 12-bit plus sign successive approximation analog-to-digital converter (ADC) designed on the iCMOS (industrial CMOS) process. This technology combines high voltage silicon with submicron CMOS and complementary bipolar technologies, enabling high performance analog ICs capable of operating at up to 33 V in a compact footprint. The AD7323 is particularly notable for its ability to accept true bipolar analog input signals and its low power consumption of 18 mW at a maximum throughput rate of 500 kSPS.
