Applications
The TDA2228M is designed for use in monophonic television receiver sound channels, handling everything from IF amplification to FM demodulation and audio output. It is well suited for CRT-based TV sets, retro electronics repair, and educational audio circuit designs where a self-contained sound IF solution in a DIP package is required.

Frequently Asked Questions
What supply voltage does the TDA2228M require for normal operation?
The TDA2228M is designed to operate from a 12 V supply rail, which is standard in television receiver power systems. This single-supply operation simplifies the power design, as no negative rail or dual supply is needed to run the full sound IF demodulation and amplification chain.
What package does the TDA2228M use, and how does it affect PCB assembly?
The TDA2228M comes in a Dual-In-Line (DIP) through-hole package, which allows hand soldering and easy insertion into standard 0.1-inch pitch sockets. This 14-pin or 16-pin DIP form factor is ideal for prototype builds, repair work on classic TV sets, and educational circuit demonstrations where surface-mount soldering tools are unavailable.
In which TV audio circuit stages can the TDA2228M replace older discrete designs?
The TDA2228M integrates the complete 5.5 MHz or 6.0 MHz sound IF amplification and FM demodulation stages, which in older designs required 5 to 8 discrete transistors and tuned coils. By replacing that discrete chain with a single IC, designers reduce the component count by at least 10 parts and improve channel-to-channel consistency across production units.
