The LT6600CS8-2.5#PBF is a very low noise, fully Differential Amplifier with a 4th order 2.5MHz low pass filter approximating a Chebyshev frequency response. Most differential amplifier require many precision external components to tail/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 provides the necessary level shifting to set its output common mode voltage to accommodate the reference voltage requirements of A/Ds. Using a proprietary internal architecture, the LT6600-2.5 integrates an anti-aliasing filter and a differential amplifier/driver without compromising distortion or low noise performance. At unity gain the measured in band signal-to-noise ratio is an impressive 86dB.
