BD3426K

The BD3426K is a kind of SCF built-in sound processor for car audio.

There are some features of BD3426K as follows: (1)noise reduction for the gain switching through the soft switching circuit; (2)loudness is volume attenuation linked type and the frequency characteristics are determined by the externally mounted parts; (3)use the Bi-CMOS process; (4)control voltage of BD3426K is 3.3-5.0 V with 2-wire serial control.

What comes next is about the absolute maximum ratings of BD3426K: (1)applied voltage, VCC: 10.0 V; (2)input voltage, Vin: VCC+0.3 to GND-0.3 V; (3)power dissipation, Pd: 1060 mW; (4)operating temperature, Topr: -40 to +85; (5)storage temperature, Tstg: -55 to +150. Then is about the operating voltage range: the minimum power supply voltage (VCC) is 7.5 V, the typical is 8.5 V and the maximum is 9.5 V.
