The TLV1018 can also be used outside of an ECM as a space saving external preamplifier. In this application,
the TLV1018 follows a phantom biased JFET microphone in the circuit. This is shown in Figure 6. The input of
the TLV1018 is connected to the microphone via the 2.2-
F capacitor. The advantage of this circuit over one with
only a JFET microphone are the additional gain and the high-pass filter supplied by the TLV1018. The high-pass
filter makes the output signal more robust and less sensitive to low frequency disturbances. In this configuration,
the TLV1018 should be placed as close as possible to the microphone.
