LMH6642EP/LMH6643EP/LMH6644EP
Enhanced Plastic Low Power, 130MHz, 75mA Rail-to-Rail
Output Amplifiers
General Description
The LMH664XEP 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.
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.
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 150load 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.
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 (150) and through-
out the output voltage range. The LMH664XEP family is
offered in single (LMH6642EP), dual (LMH6643EP), and
quad (LMH6644EP) options. See ordering information for
packages offered.
