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 VOS,
±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.

Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5kΩ in series with 100pF.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) - TA)/ θJA . All numbers apply for packages soldered directly onto a PC board.
Note 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: Average drift is determined by dividing the change in parameter at temperature extremes into the total temperature change.
Note 8: Slew rate is the slowest of the rising and falling slew rates.
Note 9: Machine Model, 0Ω in series with 200pF.
Note 10: Simulation results.
Note 11: Short circuit test is a momentary test. Output short circuit duration is 1.5ms.
Note 12: Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of
the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA.
Absolute maximum ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.
