3 Description
The LMH6624 and LMH6626 devices offer wide
bandwidth (1.5 GHz for single, 1.3 GHz for dual) with
very low input noise (0.92 nV/√Hz, 2.3 pA/√Hz) and
ultra-low dc errors (100 μV V_OS, ±0.1 μV/°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 (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 and LMH6626 devices operate from
±2.5 V to ±6 V in dual supply mode and from 5 V to
12 V 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.
