The LMH664XEP 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.
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 150Ω load and A
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.
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 LMH664XEP family is
offered in single (LMH6642EP), dual (LMH6643EP), and
quad (LMH6644EP) options. See ordering information for
packages offered.
