Overview
The AD1674JNZ is a 12-bit, 100 kSPS analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the AD1674 family, which is known for its multipurpose and high-performance capabilities. The AD1674JNZ includes a user-transparent on-board sample-and-hold amplifier (SHA), a 10-volt reference, and clock and three-state output buffers for microprocessor interface. It is pin compatible with industry standards such as the AD574A and AD674A but offers a faster conversion rate and integrated sampling function.
