LTC6406: 133MHz Differential Amplifier with External Gain Set, Impedance Matching to a 75Ω Source and Level Shifting

This circuit shows an example of a single-ended-to-differential amplifi er matching a 75Ω source and level shifting from a 2.5V input common mode to a 1.25V output common mode voltage (typical level shifting required from a 5V single-ended circuit to a 3V differential circuit to drive a high speed ADC). The singleended- to-differential gain of the amplifier is 2 (the 1VP-P input signal is amplifi ed into a 2VP-P differential output signal, a typical input voltage range of a high speed ADC).
