iC-TW2 8-BIT SIN/COS INTERPOLATION IC
WITH INTEGRATED EEPROM
TYPICAL APPLICATIONS
Rev D3, Page 28/30
The circuit in Figure 21 depicts a typical application.
Differential sensor signals (or differential SIN / COS
encoder signals) are directly connected to the iC-TW2.
Index gating is single ended active low as is frequently
the case when using a HALL switch. The VC signal
of 1.21 V is used to bias the positive input PINZ. It is
recommended to decouple VC with a small capacitor
when it is used as a reference. When VC is left uncon-
nected, no capacitor is required.
