Overview
The AD1674BRZ is a 12-bit, 100 kSPS (kilosamples per second) 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 clock along with three-state output buffers for microprocessor interface. The AD1674BRZ is pin compatible with industry-standard ADCs like the AD574A and AD674A but offers a faster conversion rate and includes a sampling function.
The device is fabricated using Analog Devices' BiMOS II process, which combines high-performance bipolar analog circuitry with digital CMOS logic on the same die. This integration enhances the overall performance and versatility of the ADC.
