Overview
The LM6211MF/NOPB is a wide bandwidth, low noise operational amplifier (op amp) manufactured by Texas Instruments. It is designed to operate with a single supply voltage ranging from 5V to 24V and is unity gain stable. The LM6211 features a ground-sensing CMOS input stage and offers rail-to-rail output swing, making it ideal for high voltage, low noise systems. This op amp is particularly suited for applications requiring very low input bias currents and large output voltage swings, such as active loop-filters for wide-band PLLs and high fidelity audio amplifiers.
