TDA75610SLV 2 4 x 45 W power amplifier with full I C diagnostics, high efficiency and low voltage operation Datasheet - production data Improved SVR suppression during battery transients Capable to operate down to 6 V (e.g. Start-stop) 0 03 Flexiwatt27 (Horiz.) Flexiwatt27 (SMD) Description The TDA75610SLV is a new quad bridge car radio amplifier, designed in BCD technology, in order to PowerSO36 Flexiwatt27 (Vert.) include a wide range of innovative features in a very compact and flexible device. Features The TDA75610SLV is equipped with the most complete diagnostics array that communicates Multipower BCD technology 2 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, High efficiency (class SB) thanks to the patented class SB efficiency High output power capability 4x25 W/4 concept. TDA75610SLV has been designed to be 14.4 V, 1 kHz, 10% THD, 4 x 45 W max power very robust against several kinds of 2 driving capability (64 W max power) misconnections. It is moreover compliant to the 2 most recent OEM specifications for low voltage Full I C bus driving: operation (so called start-stop battery profile Standby during engine stop), helping car manufacturers to Independent front/rear soft play/mute reduce the overall emissions and thus Selectable gain 26 dB /16 dB (for low noise contributing to environment protection. The ST line output function) BCD in combination with class SB efficiency and High efficiency enable/disable intelligent power has been sold in million of units 2 I C bus digital diagnostics (including DC to most known car manufacturers, the and AC load detection) TDA75610SLV is the latest and most compact member of this power amplifiers family.
