Amplifi er and 5MHz Lowpass Filter
DESCRIPTION
The LT
4th order 5MHz lowpass fi lter approximating a Chebyshev
frequency response. Most differential amplifi ers require
many precision external components to tailor gain and
bandwidth. In contrast, with the LT6600-5, two external
resistors program differential gain, and the fi lter’s 5MHz
cutoff frequency and passband ripple are internally set.
The LT6600-5 also provides the necessary level shifting
to set its output common mode voltage to accommodate
the reference voltage requirements of A/Ds.
Using a proprietary internal architecture, the LT6600-5
integrates an anti-aliasing fi lter and a differential ampli-
fi er/driver without compromising distortion or low noise
performance. At unity gain the measured in band sig-
nal-to-noise ratio is an impressive 82dB. At higher gains
the input referred noise decreases so the part can process
smaller input differential signals without signifi cantly
degrading the output signal-to-noise ratio.
The LT6600-5 also features low voltage operation. The
differential design provides outstanding performance for
a 2V
3V supply.
For similar devices with other cutoff frequencies, refer to
the LT6600-20, LT6600-10 and LT6600-2.5.
