Figure 28 is a typical circuit connection diagram for which the cutoff frequency of the input HPF is about 5 Hz.
(1) Bypass capacitor = 0.1- µ F ceramic and 10- µ F tantalum, depending on layout and power supply.
(2) A 1- µ F capacitor gives a 5.3-Hz cutoff frequency for the input HPF in normal operation and requires a power-on
settling period with a 30-ms time constant during power-on initialization.
