TDA7391LV Differential input, single BTL output power amplifier with st-by, clip detection and start stop compatibility

The TDA7391LV is a bridge class AB audio power amplifier specially intended for car radio high power 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 boosters and 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 (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection

技术特性

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:
- No bootstrap capacitors
- No boucherot cells
- Internally fixed gain (30 dB)
- No SVR capacitor
Standby function (CMOS compatible)
Programmable turn-on/off delay
Capable to operate to 6 V (e.g. “start-stop”)
Protections
- Short circuit (to GND, to VS, across the load)
- Very inductive loads
- Chip over temperature
- Load dump
- Open GND
- ESD
