Real Time Clocks

Reference Design Library Digi-Key's Reference Design Library contains technical blueprints that have been designed and verified to solve system-level problems and reduce time-to-market. Learn More Stability 101: Driving a Capacitive Load (Operational Amplifiers) Analog Devices’ Matt Duff explains why it’s a bad idea to drive a capacitor directly with an operational amplifiers (on amp) and why putting a resistor between the op amp and capacitor can makes the circuit stable. Learn More On-Demand Designing Safety Critical Applications Webinar Microchip reviews how to ensure safe microcontroller operation and design practices using diagnostic test libraries, FMEDAs, and other recommended tools.
