LA4627
Monolithic Linear IC
2-Channel AF Power Amplifier
Overview
The LA4627 is a 2-channel power amplifier developed for use in radio/cassette player products. The LA4627 reduces the
number of required external components by 50% over earlier products (BS/NF capacitors and oscillation prevention RC
components) and thus can contribute significantly to space saving in end products.
Features
• Provided in the DIP12F.
• PO : 2.0W×2 (VCC = 9V, RL = 4Ω)
2.5W×2 (VCC = 9V, RL = 3Ω)
• Standby function built in (supports direct microcontroller control).
• Built-in thermal protection circuit.
