ADI LT6600IS8-5#PBF

The LT6600 - 5 combines a fully differential amplifier with a 4th order 5MHz 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 - 5, two external resistors program differential gain, and the filter’s 5MHz cutoff frequency and passband ripple are internally set. The LT6600 - 5 also 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 - 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 82dB. At higher gains the input referred noise decreases so the part can process smaller input differential signals without significantly degrading the output signal - to - noise ratio. The LT6600 - 5 also features low voltage operation. The differential design provides outstanding performance for a 2VP - P signal level while the part operates with a single 3V supply.
