TDA7569BLV STMicroelectronics

TDA7569BLV 2 4 x 50 W power amplifier with full I C diagnostics, high efficiency and low voltage operation Datasheet - production data Very robust against misconnections Improved SVR suppression during battery transients Capable to operate down to 6 V (e.g. Start- Flexiwatt27 (Horiz.) Flexiwatt27 (SMD) stop) Description The TDA7569BLV is the most advanced BCD 0 03 technology quad bridge car radio amplifier of his PowerSO36 Flexiwatt27 (Vert.) family, including a wide range of innovative features. The TDA7569BLV is equipped with the most Features complete diagnostics array that communicates 2 Multipower BCD technology the status of each speaker through the I C bus. MOSFET output power stage The dissipated output power under average DMOS power output listening condition is significantly reduced when compared to the conventional class AB solutions, Class SB high efficiency thanks to the patented solution. Moreover it has High output power capability 4x28 W/4 been designed to be very robust against several 14.4 V, 1 kHz, 10% THD, 4 x 45 W max power kinds of misconnections. Max power 4 x 72 W / 2 It is moreover compliant to the most recent OEM 2 Full I C bus driving: specifications for low voltage operation (so called Standby start-stop battery profile during engine stop and re-start), helping car manufacturers to reduce the Independent front/rear soft play/mute overall emissions and thus contributing to Selectable gain 26 dB /16 dB (for low noise environment protection. line output function) High efficiency enable/disable Figure 1.
