LMH6611/LMH6612
Single Supply 345 MHz Rail-to-Rail Output Amplifiers
General 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/
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 VPP into 150Ω allows the am-
plifiers 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 150
Ω load the out-
put swings to within 49 mV of the ground, while a mid-rail
terminated 1 k
Ω load will swing to 77 mV of either rail.
The amplifiers will operate on a 2.7V to 11V single supply or
±1.35V to ±5.5V split supply. The LMH6611 single is available
in 6-Pin TSOT23 and has an independent active low disable
pin which reduces the supply current to 120 A. The
LMH6612 is available in 8-Pin SOIC. Both the LMH6611 and
LMH6612 are available in 40°C to +125°C extended indus-
trial temperature grade.
