Moreover, the book has an appendix that contains a case study. There is only one mounting type recommended for the product, which is Surface Mount. There is a 28-SOIC (0.295, 7.50mm Width) case embedded in it. In this case, the device has 2 channels. There are Audio Signal Processor functions included in this part for your reference. This device can be applied in both Audio Systems and X directions. As far as I know, it is supplied within 6V~10.2V days. In this device, the temperature range is -40°C~85°C TA, which is the range of this device. There are 28 terminations on the chip, which is the number of terminations on the chip. You can find similar parts by searching for the TDA7348 family of parts. The chip has 28 pins that are accessible from the outside. In order to sort a part based on its consumer IC type, TONE CONTROL CIRCUIT can be used. There should be a minimum supply voltage (Vsup) for this part, which should not be less than 6V volts. Family Audio Control ICs is what we're talking about. It can give voltage up to 9V volts. On the side of it, there are 2 bands.
TDA7348D Features
