Overview
The AD1674, part number 5962-9316401MXA, is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to be a complete, multipurpose ADC, featuring a user-transparent on-board sample-and-hold amplifier (SHA), a 10-volt reference, and a clock along with 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 includes a sampling function. The AD1674 is fully specified for both ac and dc parameters, making it ideal for signal processing and traditional dc measurement applications.
