LTC1152CN8

精密放大器 LTC1152 - Rail-to-Rail Input Rail-to-Rail Output Zero-Drift Op Amp

DESCRIPTION

The LTC®1152 is a high performance, low power zero-drift op amp featuring an input stage that common modes to both power supply rails and an output stage that provides rail-to-rail swing, even into heavy loads. The wide input common-mode range is achieved with a high frequency on-board charge pump. This technique eliminates the crossover distortion and limited CMRR imposed by competing technologies. The LTC1152 is a C-LoadTM of amp, enabling it to drive any capacitive load.
