THEORETICAL VOLTAGE ON PIN 2

TEA7530
- The value of R affects the system time con-
stant and the charge/discharge duty cycle.
- The value of C only affects the system time
constant.
- R should be greater or equal to 150KΩ for cor-
rect AGC operation.
PIN 3: CIRCUIT SUPPLY VOLTAGE
With pin 8 open circuit, VLS is internally stabilized
at 3V.
When the TEA7530 is under AGC control, the
voltage on this pin varies slightly (due to AGC ac-
tion).
PIN 4: EARPHONE INPUT
Input for loudspeaker signal
Pin 2
7/11
