Most differential amplifiers require many precision external ponents to tailor gain and bandwidth. In contrast, with the LT6600-10, two external resistors program differential gain, and the filter’s 10MHz cutoff frequency and passband ripple are internally set. The LT6600-10 also provides the necessary level shifting to set its output mon mode voltage to acmodate 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 promising distortion or low noise performance. At unity gain the measured in band signal-to-noise ratio is an impressive 82d B. 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 LT6600-10 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. For similar devices with other cutoff frequencies, refer to the LT6600-20 and LT6600-2.5.
