TDA7569BDLVPD 2 4 x 50 W differential power amplifier with full I C diagnostics, high efficiency and low voltage operation Datasheet - production data Clipping detector pin with selectable threshold (2 %/10 %) Standby/mute pin Linear thermal shutdown with multiple thermal 0 03 warning 3RZHU62 VOXJ XS ESD protection Very robust against any kind of misconnection Improved SVR suppression during battery Features transients Multipower BCD technology Capable to play down to 6 V (e.g. Start-stop) MOSFET output power stage DMOS power output Description Differential input The TDA7569BDLVPD is the most advanced Class SB high efficiency BCD technology quad bridge car radio amplifier, including a wide range of innovative features. High output power capability: 4x28 W/4 14.4 V, f = 1 kHz, 10% THD The TDA7569BDLVPD is equipped with the most complete diagnostics array that communicates 4x50 W/2 14.4 V, f = 1 kHz, 10% THD 2 the status of each speaker through the I C bus. Max power 4 x 75 W / 2 The differential input stage improves the 2 Full I C bus driving: disturbance rejection. Standby The dissipated output power under average Independent front/rear soft play/mute listening condition is significantly reduced when Selectable gain 26 dB /16 dB (for low noise compared to the conventional class AB solutions, line output function) thanks to the innovative internal design. Moreover High efficiency enable/disable it has been designed to be very robust against 2 several kinds of misconnections. I C bus digital diagnostics (including DC bus AC load detection) It is moreover compliant to the most recent OEM Fault detection through integrated diagnostics specifications for low voltage operation (so called start-stop battery profile during engine stop), DC offset detection helping car manufacturers to reduce the overall Four independent short circuit protection emissions and thus contributing to environment protection.
