... LT6604-15 APPLICATIONS INFORMATION In Figure 3 the LT6604-15 is providing 12dB of gain. The gain resistor has an optional 62pF in parallel to improve the passband fl atness near 15MHz. The common mode output voltage is set to 2V. Use Figure 4 to determine the interface between the LT6604-15 and a current output DAC. The gain, or “tran- simpedance,” ...

... LT6604-15 APPLICATIONS INFORMATION Common Mode DC Currents In applications like Figure 1 and Figure 3 where the LT6604-15 not only provides lowpass fi ltering but also level shifts the common mode voltage of the input signal, DC currents will be generated through the DC path between input and output terminals. Minimize these currents to decrease power dissipation and distortion ...
