The LM6211 is a wide bandwidth, low noise op amp with a wide supply voltage range and a
low input bias current. The LM6211 operates with a single supply voltage of 5V to 24V, is unity
gain stable, has a ground-sensing CMOS input stage, and offers rail-to-rail output swing.
The LM6211 is designed to provide optimal performance in high voltage, low noise systems.
The LM6211 has a unity gain bandwidth of 20 MHz and an input referred voltage noise density of 5.5
nV/√Hz at 10 kHz. The LM6211 achieves these specifications with a low supply
current of only 1 mA. The LM6211 has a low input bias current of 2.3 pA, an output short circuit
current of 25 mA and a slew rate of 5.6 V/us. The LM6211 also features a low common-mode input
capacitance of 5.5 pF which makes it ideal for use in wide bandwidth and high gain circuits. The
LM6211 is well suited for low noise applications that require an op amp with very low input bias
currents and a large output voltage swing, like active loop-filters for wide-band PLLs. A low total
harmonic distortion, 0.01% at 1 kHz with loads as high as 600Ω, also makes the LM6211 ideal for
high fidelity audio and microphone amplifiers.
The LM6211 is available in the small SOT-23 package, allowing the user to implement
ultra-small and cost effective board layouts.
