TDA7391LV 40 W bridge car radio amplifier with low voltage operation Datasheet - production data Protections: Short circuit (to GND, to V , across the S load) Very inductive loads Chip over temperature YHUWLFDO 0XOWLZDWW Load dump Open GND ESD 3RZHU62 3RZHU62 VOXJ GRZQ VOXJ XS * 3*36 Description The TDA7391LV is a bridge class AB audio power Features amplifier for car radio applications. High power capability: The high power capability together with the 40 W/ 4 max possibility to operate either in differential input mode or single ended input mode makes it 45 W/ 3.2 max suitable for high end car radio equipment. The 32 W/ 3.2 V = 14.4 V, f = 1 kHz, S exclusive fully complementary output stage and THD = 10 % the internal fixed gain configuration drop the 26 W/ 4 V = 14.4 V, f = 1 kHz, S external component count. THD = 10% The on board clipping detector allows easy Differential inputs (either single ended or implementation of gain compression systems. differential input signal is accepted) It is moreover compliant to the most recent OEM Minimum external component count specifications for low voltage operation ( start- Standby function (CMOS compatible) stop battery profile during engine stop), and e-call Capable to operate to 6 V - start-stop and functions. e-call compatibility Table 1.
