LT6600-20
Very Low Noise, Differential
Amplifier and 20MHz Lowpass Filter
FEATURES DESCRIPTION n The LT®6600-20 combines a fully differential amplifier with a
4th order 20MHz lowpass filter approximating a Chebyshev
frequency response. Most differential amplifiers require
many precision external components to tailor gain and
bandwidth. In contrast, with the LT6600-20, two external
resistors program differential gain, and the filter’s 20MHz
cutoff frequency and passband ripple are internally set.
The LT6600-20 also provides the necessary level shifting
to set its output common mode voltage to accommodate
the reference voltage requirements of A/Ds. n n Programmable Differential Gain via Two External
Resistors
