FEATURES  
DESCRIPTION  
23  
900MHz 3dB bandwidth (AV = 1)  
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.  
Large signal bandwidth and slew rate 100%  
tested  
280MHz 3dB bandwidth (AV = +2, VOUT = 2VPP  
90mA linear output current  
1400V/μs slew rate  
)
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.  
Unity gain stable  
<1mV input Offset voltage  
7mA Supply current (no load)  
6.6V to 12V supply voltage range  
0.01%/0.026° differential gain/phase PAL  
3.1nVHz voltage noise  
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.  
Improved replacement for CLC440, CL420,  
CL426  
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.  
APPLICATIONS  
Test equipment  
IF/RF amplifier  
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.
