It has a ground Circuit Current (no signal): 25mA (Typ) isolation amplifier when connecting with external voice Total Harmonic Distortion: 0.0004%(Typ) inputs such as portable audio and car navigation. Also, Maximum Input Voltage: 2.35Vrms (Typ) BD3460FS has a volume switching shock sound Cross-talk Between Selectors: -105dB (Typ) prevention technique called Advanced Switch, Volume Control Range: +23dB to -79dB supporting the construction of high quality car audio Output Noise Voltage: 1.9Vrms(Typ) space by simple control. Residual Output Noise Voltage: 1.6Vrms (Typ) Operating Temperature Range: -40C to +85C Features Reduce switching noise of volume by using Package W(Typ) x D(Typ) x H(Max) Advanced Switch circuit. Built-in buffered stereo ground isolation amplifier inputs, ideal for external input. Energy-saving design resulting in low-current consumption by utilizing the Bi-CMOS process. It has the advantage in quality over scaling down the power heat control of the internal regulators. Arranges all I/O terminals together for easier PCB layout and smaller PCB area. 2 I C BUS can be controlled by 3.3V / 5V. Applications SSOP-A24 10.00mm x 7.80mm x 2.10mm It is optimal for car audio. It can also be used for car navigation, audio equipment of mini Compo, micro Compo, DVD, TV, etc. Typical Application Circuit FIL GND SDA SCL CS VCC OUTF1 OUTF2 OUTR1 OUTR2 OUTS1 OUTS2 10 0.1 10 4.7 4.7 4.7 4.7 4.7 4.7 2.2K 22 21 20 19 18 17 16 15 14 13 24 23 VCC VCC/2 GND 2 I C BUS LOGIC 6 ch Volume ++2323dBdB to --7799dBB / /11dBdB step,- Advanced switch circuit BUFFERED BUFFERED GND ISO AMP GND ISO AMP 100k 100k 100k 100k 100k 100k 100k 100k 100k 100k 100k Unit R : 1 2 3 4 5 6 7 8 9 10 11 12 C : F 1 1 1 1 1 1 4.7 4.7 10 10 10 10 INF1 PIN1 INF2 INR1 INR2 INS1 INS2 PIN2 NIN2 DIFFOUT2 DIFFOUT1 NIN1 Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0C2C0E100350-1-2 2015 ROHM Co., Ltd.
