Overview
The AD7321BRUZ-REEL7 is a 12-bit, 2-channel successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This component is designed using the iCMOS (industrial CMOS) process, which combines high voltage silicon with submicron CMOS and complementary bipolar technologies. This allows the ADC to accept bipolar input signals, providing high performance, low power consumption, and a compact footprint. The AD7321BRUZ-REEL7 features a high-speed serial interface and can operate at throughput rates up to 500 kSPS. It includes a 2.5 V internal reference and supports external reference operation. The device is available in a 14-lead TSSOP package and operates over a temperature range of -40°C to +85°C.
