LMH6642/6643/6644  
3V, Low Power, 130MHz, 75mA Rail-to-Rail Output  
Amplifiers  
in single (LMH6642), dual (LMH6643), and quad (LMH6644)  
options. See ordering information for packages offered.  
General Description  
The LMH664X family true single supply voltage feedback  
amplifiers offer high speed (130MHz), low distortion  
(−62dBc), and exceptionally high output current (approxi-  
mately 75mA) at low cost and with reduced power consump-  
tion when compared against existing devices with similar  
performance.  
Features  
(VS  
=
5V, TA = 25˚C, RL = 2kΩ, AV = +1. Typical values  
unless specified).  
n −3dB BW (AV = +1)  
130MHz  
3V to 12.8V  
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 for a multitude of industrial and  
commercial applications.

n THD (5MHz, RL = 2kΩ, VO = 2VPP, AV = +2)  
n Settling time  
−62dBc  
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 set-  
ting 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.  
n Fully characterized for 3V, 5V, and 5V  
n Overdrive recovery  
100ns  
n Output short circuit protected (Note 11)  
n No output phase reversal with CMVR exceeded  
Applications  
n Active filters  
n CD/DVD ROM  
n ADC buffer amp  
n Portable video  
n Current sense buffer  
This device family offers professional quality video perfor-  
mance 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 through-  
out the output voltage range. The LMH664X family is offered  
Closed Loop Gain vs. Frequency for Various Gain
