Datasheet Linear Technology LT6604CUFF-10#PBF

LT6604-10
Dual Very Low Noise,
Differential Amplifier and
10MHz Lowpass Filter
DESCRIPTION FEATURES
n The LT®6604-10 consists of two matched, fully differential
amplifiers, each with a 4th order, 10MHz lowpass filter. The
fixed frequency lowpass filter approximates a Chebyshev
response. By integrating a filter and a differential amplifier, distortion and noise are made exceptionally low. At
unity gain, the measured in band signal-to-noise ratio is
an impressive 82dB. At higher gains, the input referred
noise decreases, allowing the part to process smaller
input differential signals without significantly degrading
the signal-to-noise ratio. Dual Differential Amplifier with 10MHz Lowpass Filters
