Sales Briefcase
  • The TDA7391LV is a bridge class AB audio power amplifier for car radio applications.

    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.
    The on board clipping detector allows easy implementation of gain compression systems.
    It is moreover compliant to the most recent OEM specifications for low voltage operation ('start-stop' battery profile during engine stop), and e-call functions.

    Key Features

    • 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%
    • Differential inputs (either single ended or differential input signal is accepted)
    • Minimum external component count
    • Standby function (CMOS compatible)
    • Capable to operate to 6 V - ‘start-stop’ and ‘e-call’ compatibility
    • Protections:
      • Short circuit (to GND, to VS, across the load)
      • Very inductive loads
      • Chip over temperature
      • Load dump
      • Open GND
      • ESD
