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
Description
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.
