LMH6624
Ultra Low Noise Wideband Operational Amplifier
General Description
The LMH6624 combines wide bandwidth (1.5 GBW) with
very low input noise (0.92nV/
, 2.3pA/
) and ultra
low dc errors (100µV V
OS
,
±
0.1µV/˚C drift) providing a very
precise operational amplifier with wide dynamic range. This
enables the user to achieve closed-loop gains of greater
than 10.
The LMH6624’s traditional voltage feedback topology pro-
vides the following benefits: balanced inputs, low offset volt-
age and offset current, very low offset drift, 81dB open loop
gain, 95dB common mode rejection ratio, and 88dB power
supply rejection ratio.
The LMH6624 operates from
±
2.5V to
±
6V in dual supply
mode and from +5V to +12V in single supply configuration.
The LMH6624 is stable for closed-loop gain of A

LMH6624 is offered in SOT23-5 and SOIC-8 packages.
