LM6211 Low Noise, RRO Op-Amp with CMOS Input and 24V Operation
May 2006
LM6211
Low Noise, RRO Operational Amplifier with CMOS Input
and 24V Operation
General Description
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
at 10 kHz. The LM6211
noise density of 5.5 nV/
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
600鈩? also makes the LM6211 ideal for high fidelity audio
and microphone amplifiers.
The LM6211 is available in the small SOT package, allowing
the user to implement ultra-small and cost effective board
layouts.
