●Recommended board patterns
Short GNDs at one point as this figure.
Lay out by the shortest pattern.
OUT
GND
C1 : Capacitor terminals have to be close enough to terminals of VCC and GND.
C2 : Capacitor terminals have to be close enough to terminals of VREF and GND.
R1 : Pattern area has to be small enough to reduce parasitic capacitance of RT terminal.
It is safe to pass OUT signal line under C1.
