μ
PC2533
The reference voltage of the
μ
PC2533-01 and
μ
PC2533-02 detection comparator has been internally fixed at
1.0 V.
Under the influence of R501 (5 k
) and R502 (5 k
) of the siganl meter circuit (Fig. 2-6), signal meter output voltage
and detection comparator input voltage do not perfectly coincide. For SD sensitivity setting, refer to the following
formula.
Detection comparator input voltage =
Signal meter output voltage
×
(1 +
R501
)
Value of resistor between pin 7 and GND
Remark
Because DC output is open-collector type (Active high), connect pull-up resistor to pin 10 to use.
