FEATURES  
DESCRIPTION  
The LMH664X family true single supply voltage  
feedback amplifiers offer high speed (130MHz), low  
distortion (−62dBc), and exceptionally high output  
current (approximately 75mA) at low cost and with  
reduced power consumption when compared against  
existing devices with similar performance.

−3dB BW (AV = +1) 130MHz  
Supply Voltage Range 2.7V to 12.8V  
Slew Rate (1), (AV = −1) 130V/µs  
Input common mode voltage range extends to 0.5V  
below V− and 1V from V+. Output voltage range  
extends to within 40mV of either supply rail, allowing  
wide dynamic range especially desirable in low  
voltage applications. The output stage is capable of  
approximately 75mA in order to drive heavy loads.  
Fast output Slew Rate (130V/µs) ensures large peak-  
to-peak output swings can be maintained even at  
higher speeds, resulting in exceptional full power  
bandwidth of 40MHz with a 3V supply. These  
characteristics, along with low cost, are ideal features

Settling Time 68ns  
Careful attention has been paid to ensure device  
stability under all operating voltages and modes. The  
result is a very well behaved frequency response  
characteristic (0.1dB gain flatness up the 12MHz  
under 150Ω load and AV = +2) with minimal peaking  
(typically 2dB maximum) for any gain setting and  
under both heavy and light loads. This along with fast  
settling time (68ns) and low distortion allows the  
device to operate well in ADC buffer, and high  
frequency filter applications as well as other  
applications.  
Fully Characterized for 3V, 5V, and ±5V

This device family offers professional quality video  
performance with low DG (0.01%) and DP (0.01°)  
characteristics. Differential Gain and Differential  
Phase characteristics are also well maintained under  
heavy loads (150Ω) and throughout the output  
voltage range. The LMH664X family is offered in  
single (LMH6642), dual (LMH6643), and quad  
(LMH6644) options.

(1) Slew rate is the average of the rising and falling slew rates.  
(2) Output short circuit duration is infinite for VS < 6V at room  
temperature and below. For VS > 6V, allowable short circuit  
duration is 1.5ms.
