Low Power, 130MHz, 75mA Rail-to-Rail Output Amplifiers
General Description
The LMH664X family true single supply voltage feedback am-
plifiers offer high speed (130MHz), low distortion (−62dBc),
and exceptionally high output current (approximately 75mA)
at low cost and with reduced power consumption when com-
pared against existing devices with similar performance.
Input common mode voltage range extends to 0.5V below V
40mV of either supply rail, allowing wide dynamic range es-
pecially 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 un-
der all operating voltages and modes. The result is a very well
behaved frequency response characteristic (0.1dB gain flat-
ness 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 applica-
tions 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 al-
so 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. See ordering information for packages offered.
