TDA7850LV Low voltage operation, quad BTL output with HDS/offset detection, stand-by and mute inputs

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.
