TDA73864 x 49 W quad bridge car radio amplifier
Datasheet - production data
Features High output power capability: 4 x 49 W/4 Ω max. 4 x 28 W/4 Ω @ 14.4V, 1 kHz, 10% 4 x 24 W/4 Ω @ 13.2V, 1 kHz, 10% Low distortion Low output noise Standby function Mute function Automute at min. supply voltage detection Low external component count: Internally fixed gain (26dB) No external compensation No bootstrap capacitors Protections: Output short circuit to GND, to VS, across
the load Very inductive loads Overrating chip temperature with soft
thermal limiter Load dump voltage Fortuitous open GND Reversed battery ESD
DescriptionThe TDA7386 is an AB class audio power
amplifier, packaged in Flexiwatt 25 and designed
for high end car radio applications.
Based on a fully complementary PNP/NPN
configuration, the TDA7386 allows a rail to rail
output voltage swing with no need of bootstrap
capacitors. The extremely reduced boundary
components count allows very compact sets.
