DESCRIPTION
The LMH6609 is an ultra wideband, unity gain stable,
low power, voltage feedback op amp that offers
900MHz bandwidth at a gain of 1, 1400V/μs slew rate
and 90mA of linear output current.
The LMH6609 is designed with voltage feedback
architecture for maximum flexibility especially for
active filters and integrators. The LMH6609 has
balanced, symmetrical inputs with well-matched bias
currents and minimal offset voltage.
With Differential Gain of 0.01% and Differential Phase
of 0.026° the LMH6609 is suited for video
applications. The 90mA of linear output current
makes the LMH6609 suitable for multiple video loads
and cable driving applications as well.
The supply voltage is specified at 6.6V and 10V. A
low supply current of 7mA (at 10V supply) makes the
LMH6609 useful in a wide variety of platforms,
including portable or remote equipment that must run
from battery power.
The LMH6609 is available in the industry standard 8-
pin SOIC package and in the space-saving 5-pin
SOT-23 package. The LMH6609 is specified for
operation over the -40°C to +85°C temperature
range. The LMH6609 is manufactured in state-of-the-
art VIP10™ technology for high performance.
