Overview
The LMH6611MK/NOPB is a high-performance, single supply, 345 MHz rail-to-rail output operational amplifier produced by Texas Instruments. This amplifier is designed for power-conscious single supply systems and is particularly suited for high accuracy video and test applications. It operates on a supply voltage range of 2.7V to 11V and can also function with split supplies from ±1.35V to ±5.5V. The LMH6611 features low noise, low distortion, and precision-trimmed input offset voltages, making it an ideal choice for demanding applications.
