LMH6639 www.ti.com SNOS989G – JANUARY 2002 – REVISED MARCH 2013 APPLICATION NOTES INPUT AND OUTPUT TOPOLOGY All input / output pins are protected against excessive voltages by ESD diodes connected to V+ and V- rails (see Figure 44). These diodes start conducting when the input / output pin voltage approaches 1Vbe beyond V+ or Vto protect against over voltage. These diodes are normally reverse biased.

LMH6639 SNOS989G – JANUARY 2002 – REVISED MARCH 2013 www.ti.com MULTIPLEXING 5 AND 10MHz The LMH6639 may be used to implement a circuit which multiplexes two signals of different frequencies. Three LMH6639 high speed op-amps are used in the circuit of Figure 46 to accomplish the multiplexing function. Two LMH6639 are used to provide gain for the input signals, and the third device is used to provide output gain for the selected signal.
PAGE 17
LMH6639 www.ti.com SNOS989G – JANUARY 2002 – REVISED MARCH 2013 In the circuit of Figure 46, the outputs of IC1 and IC2 are tied together such that their output impedances are placed in parallel at the input of IC3. The output impedance of the disabled amplifier is high compared both to the output impedance of the active amplifier and the 330Ω gain setting resistors. The closed loop output resistance for the LMH6639 is around 0.2Ω.
