Product Summary

The TDA1554Q is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) plastic power package. The circuit contains 4× 11 W single-ended or 2 ×22 W bridge amplifiers. The TDA1554Q is primarily developed for car radio applications.

Parametrics

TDA1554Q absolute maximum ratings: (1)Supply voltage, operating, VP: 18 V; non-operating VP: 30 V; load dump protected during 50 ms; tr ≥ 2.5 ms, VP: 45 V; (2)Non-repetitive peak output current, IOSM: 6A; (3)Repetitive peak output current, IORM: 4A; (4)Storage temperature range, Tstg: -55 + 150℃; (5)Junction temperature, Tj: 150℃; (6)AC and DC short-circuit-safe voltage, VPSC: 18 V; (7)Energy handling capability at outputs: 200 mJ; (8)Reverse polarity, VPR: 6V; (9)Total power dissipation, Ptot: 60 W.

Features

TDA1554Q features: (1)Requires very few external components; (2)Flexibility in use-Quad single-ended or stereo BTL; (3)High output power; (4)Low offset voltage at outputs (important for BTL); (5)Fixed gain; (6)Good ripple rejection; (7)Mute/stand-by switch; (8)Load dump protection; (9)AC and DC short-circuit-safe to ground and VP; (10)Thermally protected; (11)Reverse polarity safe; (12)Capability to handle high energy on outputs (VP = 0 V); (13)Protected against electrostatic discharge; (14)No switch-on/switch-off plop; (15)Low thermal resistance; (16)Identical inputs (inverting and non-inverting); (17)Flexible leads.
