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 ST-
BY and MUTE pins.
