TYPICAL APPLICATION
DESCRIPTION
Very Low Noise, Differential
Amplier and 15MHz Lowpass Filter
The LT6600-15 combines a fully differential amplier with a
4th order 15MHz lowpass lter approximating a Chebyshev
frequency response. Most differential ampliers require
many precision external components to tailor gain and
bandwidth. In contrast, with the LT6600-15, two external
resistors program differential gain, and the lter’s 15MHz
cutoff frequency and passband ripple are internally set.
The LT6600-15 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 LT6600-15
integrates an antialiasing lter and a differential amplier/
driver without compromising distortion or low noise perfor-
mance. At unity gain the measured in band signal-to-noise
ratio is an impressive 76dB. At higher gains the input
referred noise decreases so the part can process smaller
input differential signals without signicantly degrading
the output signal-to-noise ratio.
The LT6600-15 also features low voltage operation. The
differential design provides outstanding performance for
a 2VP-P signal level while the part operates with a single
3V supply.
The LT6600-15 is packaged in an SO-8 and is pin compat-
ible with standalone differential ampliers.
