Description

TDA2003 Car Radio Audio Amplifier

The TDA 2003 has improved performance with the same pin configuration as the TDA 2002.

The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are maintained. The device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation 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.

V_S Peak supply voltage (50ms) 40 V
V_S DC supply voltage 28 V
V_S Operating supply voltage 18 V
I_O Output peak current (repetitive) 3.5 A
I_O Output peak current (non repetitive) 4.5 A
P_tot Power dissipation at T_case = 90°C 20 W
T_stg, T_jStorage and junction temeperature -40 to 150 °C
