Technical Specifications:

The TBA222BSI operates with a supply voltage typically in the range of 4V to 15V. It delivers an output power of typically around 1 to 2 Watts into a standard loudspeaker impedance (e.g., 4 or 8 ohms). The device has internal short-circuit and thermal protection to prevent damage from overloads or overheating. The total harmonic distortion (THD) is typically low, ensuring good audio quality. The device is packaged in a SIP (Single In-line Package) or similar through-hole package for easy PCB mounting. The operating temperature range is suitable for consumer electronics applications. The gain can be adjusted by external resistors to suit different application requirements. This part is designed to provide a simple and reliable audio amplification solution with minimal external components.
