DESCRIPTION
The LMH6624/LMH6626 offer wide bandwidth
(1.5GHz for single, 1.3GHz for dual) with very low
input noise (0.92nV/√Hz, 2.3pA/√Hz) 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 voltage feedback topology provide the
following benefits: balanced inputs, low offset voltage
and offset current, very low offset drift, 81dB open
loop gain, 95dB common mode rejection 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 SOT-23-5 and SOIC-8
packages.
The LMH6626 is offered in SOIC-8 and VSSOP-8
packages.
