Product Summary

The TDA2003 is a 10W car radio audio amplifier. It has improved performance with the same pin configuration as the TDA 2002. The TDA2003 provides a high output current capability(up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation of the TDA2003 is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground.

Parametrics

TDA2003 absolute maximum ratings: (1)Peak supply voltage (50ms): 40 V; (2)DC supply voltage: 28 V; (3)Operating supply voltage: 18 V; (4)Output peak current (repetitive): 3.5 A; (5)Output peak current (non repetitive): 4.5 A; (6)Power dissipation at Tcase = 90℃: 20W; (7)Storage and junction temeperature: -40℃ to 150℃.

Features

TDA2003 features: (1)Supply voltage:8 to 18V; (2)Quiescent output voltage (pin 4): 6.1 to 7.7V; (3)Quiescent drain current (pin 5): 44 to 50mA; (4)frequency response: 40Hz to 15000Hz; (5)input resistance: 70kΩ to 150kΩ; (6)voltage gain: 39.3dB to 40.3dB; (7)input noise voltage: 1uV to 5uV; (8)input noise current: 60pA to 200pA; (9)supply voltage rejection: 30dB to 36dB.
