The LM6211MF is a single low noise Operational Amplifier with wide supply voltage range and a low input bias current. The LM6211 operates with a single supply voltage of 5 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 an unity gain bandwidth of 20MHz and an input referred voltage noise density of 5.5nV/√Hz at 10kHz. The LM6211 achieves these specifications with a low supply current of only 1mA. The LM6211 has a low input bias current of 2.3pA, an output short-circuit current of 25mA and a slew rate of 5.6V/μs. The LM6211 also features a low common-mode input capacitance of 5.5pF which makes it ideal for use in wide bandwidth and high gain circuits. It is 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.
