Volume Volume Volume Volume DatasheeDatasheett General-Purpose 4ch Electronic Volume with Built-in Advanced Switch BD3464FV General Description Key Specifications BD3464FV is a 4ch electronic volume which has the Power Supply Voltage Range: 7.0V to 9.5V best audio efficiency in the industry. It has a volume Circuit Current (no signal): 25mA (Typ) switching shock sound prevention technique called Total Harmonic Distortion: 0.0004%(Typ) Advanced Switch, supporting the construction of high Maximum Input Voltage: 2.35Vrms (Typ) quality car audio space by simple control. Cross-talk between Selectors: -105dB (Typ) Volume Control Range: +23dB to -79dB Features Output Noise Voltage: 1.9Vrms(Typ) Residual Output Noise Voltage: 1.6Vrms (Typ) Reduce switching noise of volume by using Operating Temperature Range: -40C to +85C Advanced Switch circuit. Energy-saving design resulting in low-current consumption by utilizing the Bi-CMOS process. It Package W(Typ) x D(Typ) x H(Max) 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 It is optimal for car audio. It can also be used for car navigation, audio equipment of mini Compo, micro Compo, DVD, TV, etc. SSOP-B20 6.50mm x 6.40mm x 1.45mm Typical Application Circuit FIL GND SDA SCL CS VCC OUTF1 OUTF2 OUTR1 OUTR2 10 0.1 10 4.7 4.7 4.7 4.7 2.2K 20 19 18 17 16 15 14 13 12 11 VCC VCC/2 GND 2 I C BUS LOGIC 4 ch Volume ++2323ddBB to --79d79B/B1/d1B dB stestp,ep - ,- Advanced switch circuit 100k 100k 100k 100k Unit 1 2 3 4 5 6 7 8 9 10 R : C : F 1 1 1 1 INF1 INF2 INR1 INR2 Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0C2C0E100370-1-2 2015 ROHM Co., Ltd.
