LT6600CS8-2.5#PBF

LT6600CS8-2.5#PBF combines a fully differential amplifier with a 4th order 2.5MHz lowpass filter approximating a Chebyshev frequency response. Most differential amplifiers require many precision external components to tail or gain and bandwidth. In contrast, with the LT6600-2.5, two external resistors program differential gain, and the filter’s 2.5MHz cut-off frequency and passband ripple are internally set. The LT6600-2.5 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 LT6600-2.5 integrates an antialiasing filter and a differential amplifier/driver without compromising distortion or low noise performance. Applications include high speed ADC antialiasing and DAC smoothing in networking or cellular base station applications, high speed test and measurement equipment, medical imaging, drop-in replacement for differential amplifiers.
