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 groundsensing 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/в€љHz 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 …
