Overview
The AD1674KRZ is a 12-bit, 100 kSPS (kilosamples per second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of a family of complete, multipurpose ADCs that include on-board sample-and-hold amplifiers (SHA), a 10-volt reference, and clock and three-state output buffers for microprocessor interface. The AD1674KRZ is designed to be pin-compatible with industry-standard ADCs like the AD574A and AD674A, but it offers a faster conversion rate and integrated sampling functionality.
