LT6600CS8-5#PBF

LT6600CS8-5#PBF 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 LTAt unity gain the measured in-band signal-to-noise ratio is an impressive 82dB. Typical applications include high-speed ADC antialiasing and DAC smoothing in networking or cellular base station applications, high-speed test and measurement equipment, medical imaging and drop-in replacement for differential amplifiers.
