DSL Receive Channel Applications
(Continued)
The LMH6622 is a low noise, low distortion high speed
operational amplifier. The LMH6622 comes in either SOIC-8
or MSOP-8 packages. Because two channels are available
in each package the LMH6622 can be used as a high
dynamic range differential amplifier for the purpose of driving
a high speed analog-to-digital converter. Driving a 1k
load,
the differential amplifier of Figure 3provides 20dB gain, a flat
frequency response up to 6MHz, and harmonic distortion
that is lower than 80dBc. This circuit makes use of a trans-
former to convert a single-ended signal to a differential sig-
nal. The input resistor R
IN
is chosen by the following equa-
tion,
The gain of this differential amplifier can be adjusted by R
C
and R
