TYPICAL APPLICATION
DESCRIPTION
Very Low Noise, Differential
Amplier and 2.5MHz Lowpass Filter
The LT6600-2.5 combines a fully differential amplier
with a 4th order 2.5MHz lowpass lter approximating a
Chebyshev frequency response. Most differential ampli-
ers require many precision external components to tail
or gain and bandwidth. In contrast, with the LT6600-2.5,
two external resistors program differential gain, and the
lter’s 2.5MHz cutoff frequency and passband ripple are
internally set. The LT6600-2.5 also provides the necessary
level shifting to set its output common mode voltage to ac-
commodate the reference voltage requirements of A/Ds.
Using a proprietary internal architecture, the LT6600-2.5
integrates an antialiasing lter and a differential ampli-
er/driver without compromising distortion or low noise
performance. At unity gain the measured in band signal-
to-noise ratio is an impressive 86dB. 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 LT6600-2.5 also features low voltage operation. The
differential design provides outstanding performance for a
4VP-P signal level while the part operates with a single 3V
supply. The LT6600-2.5 is available in SO-8 and DFN-12
packages.
For similar devices with higher cutoff frequency, refer
to the LT6600-5, LT6600-10, LT6600-15 and LT6600-20
data sheets.
