LT6600-2.5
Very Low Noise, Differential
Amplifier and 2.5MHz Lowpass Filter
FEATURES DESCRIPTION n The LT®6600-2.5 combines a fully differential amplifier
with a 4th order 2.5MHz lowpass filter approximating a
Chebyshev frequency response. Most differential amplifiers 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
filter’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 accommodate the reference voltage requirements of A/Ds. ±0.6dB (Max) Ripple 4th Order Lowpass Filter with
