AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems
(pdf, 228 kB)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits. -

FAQs/RAQs (3)
- I've noticed a new pinout on some of your high-speed op amps. Why the change after all these years?
- What's the difference between, power-down, shutdown, standby, sleep mode or disable?
- When running on a single supply, my op amp's output is highly distorted. Could this be some kind of headroom issue?
