Amplifier TDa2040 mono 3D board

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.

RATINGS:

Vs – Supply Voltage: 12 at 32 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

  1. some componant in partlist is difer from schematic diagram.[R2 is 20K and C6 is 100nF in schematic diagram, but in the part list R2 is 22K and C6 is 220nF].which is reyal

  2. Does TDA 2040 need a pre amp ,I want to connect to DTH audio output {sattelite reciever }.I have build a circuit ,but there is no sound yet .Do i need 2200 or 220micro F to my speaker ,pls reply
