Notes : 1. With tfly = 12 s and tI = 29 s. 2. The TDA8185I may be operated on a 5V supply directly. A 5.5 V shunt regulator is available internally for operation on higher supply voltage ; in this case an external limiting resistor is required. Without the external limiting resistor care must be taken to ensure that the supply voltage does not exceed 5.5V or the regulator will intervene and the device could be damaged.
