GENERAL DESCRIPTION
TDA1552Q
The TDA1552Q is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package.
The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration.
The device is primarily developed for car radio applications.
Features • Requires very few external components • High output power • Low offset voltage at outputs • Fixed gain • Good ripple rejection • Mute/stand-by switch • Load dump protection • AC and DC short-circuit-safe to ground and VP QUICK REFERENCE DATA PARAMETER Supply voltage range operating non-operating load dump protected Repetitive peak output current Total quiescent current Stand-by current Switch-on current Input impedance Junction temperature Stereo application Output power Supply voltage ripple rejection DC output offset voltage Channel separation Channel unbalance RS = 0 Ω f = 100 Hz to 10 kHz RR |∆VO| α |∆Gv| 48 − 40 − − − − − − 150 − 1 dB mV dB dB RL = 4 Ω; THD = 10% Po 20 22 − W IORM Itot Isb Isw |ZI| Tj − − − − 50 − − 80 0.
