Product Overview
TDA7850H is a 4 x 50W MOSFET quad bridge power amplifier. It is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/NChannel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances. It integrates a DC offset detector.
- High output power capability is 4 x 50W/4 ohm maximum
- MOSFET output power stage, excellent 2 ohm driving capability
- Hi-Fi class distortion, low output noise, ST-BY function
- Mute function, automute at minimum supply voltage detection
- Internally fixed gain (26dB), no external compensation, no bootstrap capacitors
- On board 0.35A high side driver, output short circuit to gnd, to Vs, across the load
- Very inductive loads, overrating chip temperature with soft thermal limiter
- Output DC offset detection, load dump voltage, fortuitous open gnd, reversed battery
- Quiescent current is 180mA typical at (Tamb = 25°C)
- Storage temperature range from -55°C to 150°C, flexiwatt25 (horizontal) package
