TDA7391LV

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