TDA7391LV

40 W bridge car radio amplifier with low voltage operation

Datasheet - production data

 Protections:

– Short circuit (to GND, to V_S, 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.

Features

 High power capability:

– 40 W/ 4 Ω max

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.

– 45 W/ 3.2 Ω max

– 32 W/ 3.2 Ω @ V_S= 14.4 V, f = 1 kHz,

THD = 10 %

– 26 W/ 4 Ω @ V_S= 14.4 V, f = 1 kHz,

THD = 10%

The on board clipping detector allows easy

implementation of gain compression systems.

 Differential inputs (either single ended or

differential input signal is accepted)

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.

 Minimum external component count

 Standby function (CMOS compatible)

 Capable to operate to 6 V - ‘start-stop’ and

‘e-call’ compatibility
