TDA7391PD
Description
The TDA7391PD 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.
Key Features
- High power capability: - 40 W/3.2 EIAJ - 32 W/3.2 @ VS = 14.4 V, f = 1 kHz, d = 10 % - 26 W/4 @ VS = 14.4 V, f = 1 kHz, d = 10 %
- Differential inputs (either single ended or differential input signal are accepted)
- Minimum external ponent count: - No bootstrap capacitors - No Boucherot cells - Internally fixed gain (30 dB) - No SVR capacitor
- Standby function (CMOS patible)
- Programmable turn-on/off delay
- No audible pop during mute and stand-by operations Protections
- Short circuit (to GND, to VS, across the load)
- Very inductive loads
- Chip over temperature
- Load dump
