Overview
The AD7327BRUZ is a high-performance, 8-channel, 12-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC is designed using the iCMOS (industrial CMOS) process, which combines high voltage silicon with submicron CMOS and complementary bipolar technologies. This allows the AD7327 to accept true bipolar analog input signals and provides increased performance, reduced power consumption, and a smaller package size compared to conventional CMOS processes.
The device is packaged in a 20-lead TSSOP and operates over a temperature range of -40°C to +85°C. It features a high-speed serial interface capable of throughput rates up to 500 kSPS and supports various input configurations, including single-ended, true differential, and pseudo differential inputs.
