Description
Connect a resistor between this pin and
GND1 to control the internal LPF and
trap frequencies.
Connect a 43kΩ resistor (tolerance ±2%,
temperature characteristics ±200ppm or
less).
This pin is easily affected by external
noise, so make the connection between
the pin and external resistor, and
between the GND side of the external
resistor and the GND1 pin as close as
possible.
