TC9421F

The TC9421F is a single-chip electronic volume IC incorporating an op amp circuit developed for car stereos.With a few external parts, TC9421F can control a wide range of audio functions, including main volume, balance, fader, bass, treble, loudness, and input switching.

Features of the TC9421F are:(1)input selector:Any of four input signals can be amplified with any of four gain options:0, 6,10, or 12dB; (2)incorporates op amp circuit, reducing external parts; (3)incorporates an interface for a 5V-system microcomputer; (4)the Si-gate process realizes a high-performance volume system.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

The absolute maximum ratings of the TC9421F can be summarized as:(1)supply voltage:-0.3 to 15V;(2)input voltage:-0.3 to Vdd+0.3V;(3)storage temperature:-65 to 150;(4)power dissipation:300mW;(5)operating temperature:-40 to 85.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").
