凌力尔特公司(Linear Technology Corporation)推出集成精准匹配电阻器的单位增益差动放大器LT6375,其可对小的差分信号进行精确的电平移位和缓冲,同时抑制高达±270 V的共模。A级版本实现了前所未有的性能:CMRR为97 d B(最小值)、初始增益误差为35 ppm(最大值)、共模分压比为25:1时的增益漂移为1 ppm/°C(最大值)而增益非线性为2 ppm(最大值)。
Linear Technology announces the LT6375, a unity gain differential amplifier with precision matched resistors that accurately level shifts and buffers small differential signals while rejecting common mode up to ± 270V. Class A achieves unprecedented performance with a CMRR of 97 dB (min), an initial gain error of 35 ppm (max) and a gain drift of 1 ppm / ° C at a common mode voltage division ratio of 25: 1 Maximum) and gain nonlinearity of 2 ppm (maximum).
