LTC1992-2CMS8#TR

Product Summary

The LTC1992-2CMS8#TR is a fully differential, low power amplifier. The LTC1992-2CMS8#TR is an unconstrained fully differential amplifier. The LTC1992-2CMS8#TR is fixed gain blocks (with gains of 1, 2, 5 and 10 respectively) featuring precision on-chip resistors for accurate and ultrastable gain. All of the LTC1992-2CMS8#TR has a separate internal common mode feedback path for outstanding output phase balancing and reduced second order harmonics. The VOCM pin sets the output common mode level independent of the input common mode level. This feature makes level shifting of signals easy. Applications are differential driver/receiver, differential amplification, single-ended to differential conversion, level shifting, trimmed phase response for multichannel systems.
