LMH6624/LMH6626
Single/Dual Ultra Low Noise Wideband Operational
Amplifier
General Description
The LMH6624/LMH6626 offer wide bandwidth (1.5GHz for
single, 1.3GHz for dual) with very low input noise (0.92nV/
, 2.3pA/
) and ultra low dc errors (100µV V_OS,
±0.1µV/˚C drift) providing very precise operational amplifiers
with wide dynamic range. This enables the user to achieve
closed-loop gains of greater than 10, in both inverting and
non-inverting configurations.
The LMH6624 (single) and LMH6626’s (dual) traditional volt-
age feedback topology provide the following benefits: bal-
anced inputs, low offset voltage and offset current, very low
offset drift, 81dB open loop gain, 95dB common mode rejec-
tion ratio, and 88dB power supply rejection ratio.
The LMH6624/LMH6626 operate from ± 2.5V to ± 6V in
dual supply mode and from +5V to +12V in single supply
configuration.
LMH6624 is offered in SOT23-5 and SOIC-8 packages.
The LMH6626 is offered in SOIC-8 and MSOP-8 packages.
