... The CXA1598 implements low frequency boost simply by attaching an external capacitor to the BOOST pins. Signals are boosted by approximately 6dB. The boost cut-off frequency can be freely set with the value of the external capacitor. Fig. 2. CXA1598M/S low frequency boost frequency response GND BOOST BOOST ...
