The TDA2030 chip is designed for use as a low-frequency amplifier of class AB, provides 14W of output power (d = 0.5%) at 14V (bipolar) or 28V (unipolar) supply voltage and a load of 4 ohms, guaranteed output power of 12W at 4 ohms of load and 8W at 8 ohms.
The TDA2030 provides high output current and has low harmonic and transient distortion. Short circuit protection is provided at the output. The protection module contains a device for automatically limiting the power dissipated in such a way as to keep the operating point of the output transistors within their safe operation. There is a shutdown circuit in case of overheating.
Jetbalance jb-406 amplifier is made on three TDA2030A chips
