Circuit power audio amplifier TDA2040 20 watts integrate circuit with pcb and power supply circuit

The TDA2040 is a monolithic integrated circuit in Pentawatt  package, intended for use as an audio class AB amplifier. Typically it provides 22W output power (d = 0.5%) at Vs = 32V/4Ω. The TDA2040 provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates a patented short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A thermal shut-down system is also included.

ABSOLUTE MAXIMUM RATINGS:

Vs – Supply Voltage: ± 20 V
Vi – Differential Input Voltage: ± 15 V
Io- Output Peak Current (internally limited) 4 A
Ptot – Power Dissipation at Tcase = 75 °C: 25 W
Tstg, Tj – Storage and Junction Temp. -40 to 150°C
