LT6600IS8-10#PBF

LT6600IS8-10#PBF combines a fully differential amplifier with a 4th order 10MHz lowpass filter approximating a Chebyshev frequency response. Most differential amplifiers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-10, two external resistors program differential gain, and the filter’s 10MHz cut-off frequency and passband ripple are internally set. The LT6600-10 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 LT6600-10 integrates an antialiasing filter and a differential amplifier/driver without compromising distortion or low noise performance. Typical applications are 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.
