Description
The TDA7850LV is a MOSFET class AB audio
power amplifier, designed for high-power car
radio. In addition to the outstanding output current
capability and distortion performance, the
TDA7850LV is extremely robust against several
kinds of fortuitous misconnections.
It is, moreover, compliant to the most recent OEM
specifications for low voltage operation (the so
called 'start-stop' battery profile during engine
stop) and features a very compact design in BCD
technology.
The TDA7850LV includes offset detector
capability (or high side driver output) and is
available in both SMD and standard Flexiwatt
packages.
