TDA7449 Overview

Additionally, there is a case included with the book as well. The mounting type recommended by the manufacturer is Through Hole. A 20-DIP (0.300, 7.62mm) case contains it. A 2 channel is present on the device. For your reference, this part contains Volume Control functions. Consumer Audio can be used with the device. We supply it within 6V~10.2V. Using 0°C~70°C TA as a temperature range, this device operates. It has 20 terminations. A search for parts belonging to the TDA7449 family will yield similar results. Refer to the device's specifications: 100dB. An accessible 20 pin can be found on the chip. You can use TONE CONTROL CIRCUIT to sort consumer ICs on a part. In order to operate this part, the minimum supply voltage (Vsup) must not be less than 6V volts. This part of the family is called the Audio Control ICs family. A voltage of 9V volts can be given by it. 2 bands can be seen on it.
