Description
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 STBY
and MUTE pins.
