2.7V, 650µA, 55MHz, Rail-to-Rail Input and Output  
Amplifiers with Shutdown Option  
General Description  
Features  
The LMH6645 (single) and LMH6646 (dual), rail-to-rail input  
and output voltage feedback amplifiers, offer high speed  
(55MHz), and low voltage operation (2.7V) in addition to  
micro-power shutdown capability (LMH6647, single).  
(VS = 2.7V, TA = 25˚C, RL = 1kto V+/2, AV = +1. Typical  
values unless specified).

Input common mode voltage range exceeds either supply by  
0.3V, enhancing ease of use in multitude of applications  
where previously only inferior devices could be used. Output  
voltage range extends to within 20mV of either supply rails,  
allowing wide dynamic range especially in low voltage appli-  
cations. Even with low supply current of 650µA/amplifier,

output current capability is kept at a respectable 20mA for  
driving heavier loads. Important device parameters such as  
BW, Slew Rate and output current are kept relatively inde-  
pendent of the operating supply voltage by a combination of  
process enhancements and design architecture.

Applications  
n Active filters  
n High speed portable devices  
n Multiplexing applications (LMH6647)  
n Current sense buffer  
In portable applications, the LMH6647 provides shutdown  
capability while keeping the turn-off current to less than  
50µA. Both turn-on and turn-off characteristics are well be-  
haved with minimal output fluctuations during transitions.  
This allows the part to be used in power saving mode, as  
well as multiplexing applications. Miniature packages  
(SOT23, MSOP-8, and SO-8) are further means to ease the  
adoption of these low power high speed devices in applica-  
tions where board area is at a premium.
