BD3402KS2 Overview
The book is also accompanied by a case, which only adds to the value of the book. As a mounting type, Surface Mount is recommended for it. A 64-LQFP case has been embedded with it. I have a device with 2 channels attached to it. In this part, you will find Audio Signal Processor functions that you may find useful. In addition to being used in Pre-Amplifier, the device can be used in Y as well. Votage is supplied within the specified time frame. -25°C~75°C TA is the range of temperature for this device. This chip has 64 terminations, which means it has 64 terminations on it. It is possible to sort the consumer IC type of a part using TONE CONTROL CIRCUIT. It is important that the minimum supply voltage (Vsup) for this part is greater than 8V. The voltage can be given at 59V volts. Max supply voltage (Vsup) reaches 9.5V. A 2 band is attached to it. 50mA controls the supply current. It is also possible to find IT ALSO REQUIRES 3V TO 5.5V SUPPLY on this device when using it.
