Overview
The HI3-674AKN-5 is a complete 12-bit Analog-to-Digital Converter (ADC) manufactured by Intersil, now part of Renesas Electronics. This component integrates a +10V reference, a clock, and three-state outputs, making it suitable for microprocessor-controlled applications. The ADC uses successive approximation conversion and is housed in a 28-lead DIP package. It features enhanced AC performance and freedom from latch-up due to the Dielectric Isolation process used in its bipolar analog die. The design includes a high-speed current-mode latch and a voltage comparator with high PSRR, ensuring precise conversion decisions.
