When LA is fixed externally, connect
LL to GND and UL to V
input the setting voltage to the LA pin.
Input voltage range: 0 V to 5.0 V
(V
Input voltage of V
clipped to V
When LA is fixed automatically, open
the LA pin. In this state, the LA pin is
used only for confirmation of LA width.
Non-inverted amplifier
25 dB (max)

LOW: GND
HIGH: V
Connect the peak-hold capacitor and
discharge resistor to GND, parallel to
each other.
100 kΩ/0.1µF recommended
Connect the low-pass filter capacitor
(built-in 100 kΩ resistor)
0.1µF recommended
Clip lower limit for LA
LL = 0 V to 5.0 V
When LL > UL, LA is fixed at LL value.
