AVTMOD12

POWER AMPLIFIER MODULE 2X22W WITH TDA1554

Producer: AVT

A full-fledged, stereo power amplifier. The power supply is possible from a single voltage, and the system achieves output power (about 2x20 ... 30W depending on the loudspeaker impedance). The system was designed as a small module that can be used in self-made amplification equipment or installed in a factory device, eg in place of a damaged power amplifier. The integrated circuit contains internal protection that prevents the possibility of its damage by shorting outputs or overheating.

Basic parameters:

• power supply voltage:
  • minimum: 6 VDC
  • nominal: 14.4 VDC
  • Maximum: 18 VDC
• quiescent current: typ. 80mA, max 160mA
• high output power at low power supply voltage achieved thanks to the amplifier in the bridge circuit.
• power from the battery or the AC adapter.
• cooperation with loudspeakers with impedance of 4 ohms or 8 ohms
