Description

VCC1

Pins 11 and 12 connect a

capacitor which determines the

7.5k 200

cut-off frequency for DC

12

100p

feedback block.

11 Pins 13 and 14 are input pins

1k

7.5k 200

for limiting amplifier block. Input

the signal with AC coupled.

VCS

Negative power supply for analog

block.

Positive power supply for digital

block.

Connects a resistor for alarm

VCC2 level setting.

Default voltage can be generated

without an external resistor by

shorting the VEEI pin to VEE.

SW

SW

VEE2

Generates the default voltage

between UP and DOWN.

The voltage (8.0mV for input

conversion) can be generated

between UP and DOWN (Pins 17

and 18) as alarm setting level by

connecting this pin to VEE.

Negative power supply for digital

block.
