LMH6657/LMH6658  
270MHz Single Supply, Single & Dual Amplifiers  
General Description  
Features  
The LMH6657/6658 are low-cost operational amplifiers that  
operate from a single supply with input voltage range ex-  
tending below the V−. Based on easy to use voltage feed-  
back topology and boasting fast slew rate (700V/µs) and  
high speed (140MHz GBWP), the LMH6657 (Single) and  
LMH6658 (dual) can be used in high speed large signal  
applications. These applications include instrumentation,  
communication devices, set-top boxes, etc.  
VS = 5V, TA = 25˚C, RL = 100Ω (Typical values unless  
specified)

With a -3dB BW of 100MHz (AV = +2) and DG & DP of 0.03%  
& 0.10˚ respectively, the LMH6657/6658 are well suited for  
video applications. The output stage can typically supply  
80mA into the load with a swing of about 1V from either rail.

For Industrial applications, the LMH6657/6658 are excellent  
cost-saving choices. Input referred voltage noise is low and  
the input voltage can extend below V− to ease amplification  
of low level signals that could be at or near the system  
ground. With low distortion and fast settling, LMH6657/6658  
can provide buffering for A/D and D/A applications.  
18ns  
The LMH6657/6658 versatility and ease of use is extended  
even further by offering these high slew rate , high speed Op  
Amps in miniature packages such as SOT23-5, SC70,  
SOIC-8, and MSOP-8. Refer to the Ordering Information  
section for packaging options available for each device.
