LTC1992 低功率、全差分输入 / 输出放大器 / 驱动器系列
LTC®1992 产品系列包括 5 款全差分、低功率放大器。LTC1992 是一款无约束全差分放大器。LTC1992-1、LTC1992-2、LTC1992-5 和 LTC1992-10 是固定增益部件 (增益分别为 1、2、5 和 10)，具有旨在实现准确和超稳定增益的精准片内电阻器。所有的 LTC1992 器件均具有一个单独的内部共模反馈通路，用于获得超群的输出相位平衡并降低二阶谐波。VOCM 引脚负责设定独立于输入共模电平的输出共模电平。该功能使得信号的电平移位简单易行。
这些放大器的差分输入在信号范围为轨至轨且共模电平范围为从负电源至与正电源相距 1.3V 的条件下运作。差分输入 DC 失调通常为 250µV。轨至轨输出吸收或提供 10mA 电流。对于所有高达 10,000pF 的容性负载，LTC1992 保持稳定。
LTC1992 可在电源电压低至 2.7V 的单电源应用中使用。它也可在采用高达 ±5V 的双电源的场合中使用。LTC1992 采用 8 引脚 MSOP 封装。
