Overview
The AD1674ARZ is a 12-bit, 100 kSPS (kilosamples per second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the AD1674 series, which is known for its multipurpose and high-performance capabilities. The AD1674ARZ features a user-transparent on-board sample-and-hold amplifier (SHA), a 10-volt reference, and clock along with three-state output buffers for microprocessor interface. It is pin compatible with industry-standard ADCs like the AD574A and AD674A but offers a faster conversion rate and integrated sampling function.
