Audio Accessory IC Series Ground Isolation Amplifier BA3121F, BA3123F ●Description The BA3121F/BA3123F are ground isolation amplifiers developed for use in car audio applications. This IC efficiently eliminate problems caused by wiring resistance, and remove noise generated by the electrical devices used in automobiles. The capacitance values of the external capacitors required for the ICs are small to allow compact and reliable set design. ●Features 1) Large capacitors not required 2) High common-mode rejection ratio (57dB typ. at f = 1kHz). 3) Low noise (VNO = 3.5 μVrms Typ.). 4) Low distortion (THD = 0.002% Typ.). 5) Two channels. ●Applications Car audio systems ●Line up matrix BA3121F BA3123F Operation temperature -30~+85 C -40~+85 C ●Absolute maximum ratings (Ta = 25 C) Parameter Symbol Limits Unit Power supply voltage Vcc 18 V Power dissipation Pd 450* mW Operation temperature BA3121F Topr -30~+85 ℃ BA3123F -40~+85 ℃ Storage temperature Tstg -55~+125 ℃ *Reduced by 4.5mW in Ta of 1 C over 25C. ●Recommended operating conditions (Ta = 25 C) Parameter Symbol Min. Typ. Max. Unit Power supply voltage Vcc 4 12 18 V No.09092EAT01 |
