The TDA7577BLV is a new MOSFET dual bridge amplifier specially intended for car radio applications. Thanks to the DMOS output stage the TDA7577BLV has a very low distortion allowing a clear powerful sound, together with high output power capability.
It is a very flexible device capable to support the most demanding specifications in terms of power dissipation and battery transitions: its superior efficiency performance, coming from the internal exclusive structure, can reduce the dissipated output power up to the 50 % (when compared to conventional class AB solutions). Moreover it is compliant to the recent OEM specifications thanks to the capability to work down to 6 V ('start-stop' compatibility).
This device is also equipped with a full diagnostic array that communicates the status of each speaker through the I2C bus. TDA7577BLV can also drive 1 Ω loads (with parallel connection of the outputs).
It is possible also to exclude the I2C bus interface, controlling the device by means of the usual ST-BY and MUTE pins.主な特徴
