DESCRIPTION
The LMH6611 (single, with shutdown) and LMH6612
(dual) are 345 MHz rail-to-rail output amplifiers
consuming just 3.2 mA of quiescent current per
channel and designed to deliver high performance in
power conscious single supply systems. The
LMH6611 and LMH6612 have precision trimmed
input offset voltages with low noise and low distortion
performance as required for high accuracy video, test
and measurement, and communication applications.
The LMH6611 and LMH6612 are members of the
PowerWise family and have an exceptional power-to-
performance ratio.
With a trimmed input offset voltage of 0.022 mV and
a high open loop gain of 103 dB the LMH6611 and
LMH6612 meet the requirements of DC sensitive high
speed applications such as low pass filtering in
baseband I and Q radio channels. These
specifications combined with a 0.01% settling time of
100 ns, a low noise of 10 nV/√Hz and better than 102
dBc SFDR at 100 kHz make these amplifiers
particularly suited to driving 10, 12 and 14-bit high
speed ADCs. The 45 MHz 0.1 dB bandwidth (A_V = 2)
driving 2 V_PP into 150Ω allows the amplifiers to be
used as output drivers in 1080i and 720p HDTV
applications.
The input common mode range extends from 200 mV
below the negative supply rail up to 1.2V from the
positive rail. On a single 5V supply with a ground
terminated 150Ω load the output swings to within 49
mV of the ground, while a mid-rail terminated 1 kΩ
load will swing to 77 mV of either rail.
