Overview
The AD1674KRZ-REEL is a 12-bit, 100 kSPS (kilosamples per second) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This component is part of the AD1674 series, which is designed to be a complete, multipurpose ADC. It includes a user-transparent on-board sample-and-hold amplifier (SHA), a 10-volt reference, a clock, and three-state output buffers for microprocessor interface. The AD1674 is pin compatible with industry standards such as the AD574A and AD674A but offers a faster conversion rate and a sampling function.
