LT6604-2.5
Dual Very Low Noise,
Differential Amplifier and
2.5MHz Lowpass Filter
FEATURES DESCRIPTION n The LT®6604-2.5 consists of two matched, fully differential
amplifiers, each with a 4th order, 2.5MHz 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 86dB. 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 2.5MHz Lowpass Filters
