产品详情

A 133MHz Differential Amplifier with External Gain Set, Impedance Matching to a 75Ω Source and Level Shifting

该电路示出了一款与75Ω信号源相匹配的单端至差分放大器以及从一个 2.5V 输入共模至一个 1.25V 输出共模电压的电平移位 (从一个 5V 单端电路至一个 3V 差分电路所需的典型电平移位以驱动一个高速 ADC) 实例。该放大器的单端至差分增益为 2 (1VP-P 输入信号被放大为一个 2VP-P 差分输出信号,这是高速 ADC 的一种典型的输入电压范围)。
