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
