Product Overview
TDA7851A is a class AB audio power amplifier, designed for high-power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail-to-rail output voltage swing. This, combined with high output current and minimized saturation losses, sets new power references in the car-radio field, with unparalleled distortion performance.
- Multipower BCD technology
- High output power capability of 4 x 48W/4ohm maximum
- MOSFET output power stage
- Excellent 2ohm driving capability
- Hi-Fi class distortion
- Low output noise
- Standby and mute function
- Automute at min. supply voltage detection
- Internally fixed gain (26dB), no external compensation, no bootstrap capacitors
- Flexiwatt 27 package
