TDA8424/V7,112 Overview
Moreover, the book has an appendix that contains a case study. There is only one mounting type recommended for the product, which is Through Hole. There is a 20-DIP (0.300, 7.62mm) 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 Consumer Audio and X directions. As far as I know, it is supplied within 10.8V~13.2V days. In this device, the temperature range is 0°C~70°C TA, which is the range of this device. There are 20 terminations on the chip, which is the number of terminations on the chip. You can find similar parts by searching for the TDA8424 family of parts. The following specifications are related to the device: 86dB, which can be found here. 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 10.8V volts. On the side of it, there are 2 bands. As far as the supply current is concerned, it operates under the 35mA parameter.
