This document is the data sheet of AD674B/AD774B, which introduces the features and characteristics of AD674B/AD774B, including complete monolithic 12-bit A/D converters, 8- and 16-bit microprocessor interface, 8- and 15s conversion time, -5V, -10V, 0V-10V, 0V-20V input range, commercial, industrial and military temperature range grades.
The AD674B and AD774B are complete monolithic 12-bit analog-to-digital converters designed for direct interface to 8- and 16-bit microprocessor busses. They feature a high-precision internal voltage reference and clock, requiring only power supplies and control signals for operation. These devices offer faster conversion times than the industry-standard AD574A while maintaining pin compatibility.
