LMH6733 Single Supply, 1.0 GHz, Triple Operational Amplifier
January 2007
General Description
The LMH6733 is a triple, wideband, operational amplifier designed specifically for use where high speed and low power
are required. Input voltage range and output voltage swing
are optimized for operation on supplies as low as 3V and up
to ±6V. Benefiting from National’s current feedback architecture, the LMH6733 offers a gain range of ±1 to ±10 while
providing stable operation without external compensation,
even at unity gain. These amplifiers provide 650 MHz small
signal bandwidth at a gain of 2 V/V , a low 2.1 nV/
referred noise and only consume 5.5 mA (per amplifier) from
a single 5V supply.
The LMH6733 is offered in a 16-Pin SSOP package with flow
through pinout for ease of layout and is also pin compatible
with the LMH6738. Each amplifier has an individual shutdown
pin.

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, see the Electrical Characteristics tables.

Note 4: The maximum power dissipation is a function of T
PD = (T
Note 5: 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.
Note 6: Short circuit current should be limited in duration to no more than 10 seconds. See the Power Dissipation section of the Application Section for more
details.
