TDA2002 Amplifier Schematic Circuit with explanation : electronic circuit diagrams Latest, schematics, electronic projects

This is a power amplifier circuit which built using a TDA2002 power amplifier IC module. These are replacements for the original LM383 which is no longer available. It is easy to build and has a minimum of external components. The module has both short circuit protection and thermal protection. It can drive loads as low as 1.6 ohm and is capable of delivering over 10 watts from a 16 V supply.

Rangkaian Amplifier TDA2002

The small amplifier is constructed around the TDA2002 IC, capable of delivering 4Wrms at 4ohms. The supply voltage may be anywhere between 8 and 18V, and the IC will accept transient voltage peaks of up to 28V without damage. 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.
