900MHz Voltage Feedback Op Amp
LMH6609 900MHz Voltage Feedback Op Amp
August 2003
General 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 .01 and Differential Phase of .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 recommended supply voltage range of 6V to 12V and is
specified at 6.6 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 package.
The LMH6609 is specified for operation over the -40˚C to
+85˚C temperature range. The LMH6609 is manufactured in
National Semiconductor’s state-of-the-art VIP10
ogy for high performance.
