Name
Function
1VS – POWER SUPPLY
Negative Supply Voltage.
2
NON–INV. INP. CH. 1
Channel 1 Input Signal.
3
QUIESC. CURRENT
CONTR. CAP. CH1
This capacitor works as an integrator, to control the quiescent current to output
devices in no-signal conditions on channel 1.
4
SENSE (–) CH. 1
Negative voltage sense input for overload protection and for automatic quiescent
current control.
5
ST. BY / MUTE / PLAY
Three-functions Terminal.
For VIN = 1 to 3 V, the device is in MUTE and only quiescent current flows in
the power stages ; - for VIN < 1 V, the device is in STAND-BY mode and no
quiescent current is present in the power stages ; - for VIN > 3 V, the devic
6
CURRENT PROGRAM
High Impedance Power-stages Monitor.
7
SENSE (–) CH. 2
Negative Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
8
QUIESC. CURRENT
CONTR. CAP. CH. 2
This capacitor works as an integrator, to control the quiescent current to output
devices in no-signal conditions on channel 2. If the voltage at its terminals drops
under 250 mV, it also resets the device from high-impedance state of output
stages.
9
NON–INV. INP. CH. 2
Channel 2 Input Signals.
10
Vs – POWER SUPPLY
Negative Supply Voltage.
11
INVERT. INP. CH. 2
Feedback from Output (channel 2).
12
OUT (–) CH. 2
Out Signal to Lower Driver Transistor of Channel 2.
13
OUT (+) CH. 2
Out Signal to Higher Driver Transistor of Channel 2.
14
SENSE (+) CH. 2
Positive Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
15
COMMON AC GROUND
AC Input Ground in MUTE Condition.
16
VS + POWER SUPPLY
Positive Supply Voltage.
17
SENSE (+) CH. 1
Positive Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
18
OUT (+) CH. 1
Out Signal to High Driver Transistor of Channel 1.
19
OUT (–) CH. 1
Out Signal to Low Driver Transistor of Channel 1.
20
INVERT. INP. CH. 1
Feedback from Output (channel 1).
