Overview
The LM6211MFX, produced by Texas Instruments, is a wide bandwidth, low noise operational amplifier designed for high voltage, low noise systems. It operates with a single supply voltage ranging from 5V to 24V, is unity gain stable, and features a ground-sensing CMOS input stage with rail-to-rail output swing. 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, high fidelity audio, and microphone amplifiers.
