3 Description

The

LMH6644-MIL

true

single

supply

voltage

feedback amplifier offers high speed (130 MHz), low

distortion (–62 dBc), and exceptionally high-output

current (approximately 75 mA) at low cost and with

reduced power consumption when compared against

existing devices with similar performance.

Input common mode voltage range extends to 0.5 V

extends to within 40 mV of either supply rail, allowing

wide dynamic range especially desirable in low-

voltage applications. The output stage is capable of

approximately 75 mA in order to drive heavy loads.

Fast output slew rate (130 V/µs) ensures large peak-

to-peak output swings can be maintained even at

higher speeds, resulting in exceptional full power

bandwidth of 40 MHz with a 3-V supply. These

characteristics, along with low cost, are ideal features

for

a

multitude

of

industrial

and

commercial

applications.
