LMH6609
900MHz Voltage Feedback Op Amp
General Description
Features
n 900MHz −3dB bandwidth (AV = 1)
The LMH6609 is an ultra wideband, unity gain stable, low
power, voltage feedback op amp that offers 900MHz band-
width at a gain of 1, 1400V/µs slew rate and 90mA of linear
output current.
n Large signal bandwidth and slew rate 100% tested
n 280MHz −3dB bandwidth (AV = +2, VOUT = 2VPP
n 90mA linear output current
n 1400V/µs slew rate
)
The LMH6609 is designed with voltage feedback architec-
ture for maximum flexibility especially for active filters and
integrators. The LMH6609 has balanced, symmetrical inputs
with well-matched bias currents and minimal offset voltage.
n Unity gain stable

n
1mV input Offset voltage
n 7mA Supply current (no load)
n 6V to 12V supply voltage range
n .01/ .026 differential gain/phase PAL
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 mul-
tiple video loads and cable driving applications as well.
n 3.1nV/
voltage noise
n Improved replacement for CLC440, 420, 426
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.
Applications
n Test equipment
n IF/RF amplifier
n A/D Input driver
n Active filter
n Integrator
n DAC output buffer
n Transimpedance amplifier
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 technol-
ogy for high performance.
