Description
General part information
TDA7850 Series
The TDA7850 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.The TDA7850 integrates a DC offset detector.High output power capability: 4 x 50 W/4 O max. 4 x 30 W/4 O @ 14.4 V, 1 kHz, 10 % 4 x 80 W/2 O max. 4 x 55 W/2 O @ 14.4V, 1 kHz, 10 %MOSFET output power stageExcellent 2 O driving capabilityHi-Fi class distortionLow output noiseST-BY functionMute functionAutomute at min. supply voltage detectionLow external component count: Internally fixed gain (26 dB) No external compensation No bootstrap capacitorsOn board 0.35 A high side driverProtections: 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 ESD
