Description
Positive power supply for analog block.
Switches 3.3V/5V. Short this pin
to Vcc for 3.3V between Vcc and
VEE. Leave this pin open for 5V
between Vcc and VEE.

VEE1
Pins 15 and 16 connect a
capacitor which determines the
cut-off frequency for DC
feedback block.
Pins 17 and 18 are input pins
for limiting amplifier block. Input
the signal with AC coupled.

VCS
Negative power supply for analog

Positive power supply for digital block.
No connected.
Connects a resistor for alarm
VCC2 level setting.
Default voltage can be generated
without an external resistor by
shorting the VEEI pin to VEE.

VEE2
Generates the default voltage
between UP and DOWN.
The voltage (8.0mV for input
conversion) can be generated
between UP and DOWN (Pins
22 and 23) as alarm setting level
by connecting this pin to VEE.
