Product Overview
Product Description
The LA4708N is a BTL two-channel power IC for car audio developed in pursuit of excellent sound quality. Low-region frequency characteristics have been improved through the use of a new NF capacitor-less circuit, and crosstalk which causes “muddy” sound has been reduced by improving both circuit and pattern layout. As a result, the LA4708N provides powerful bass and clear treble. In addition, the LA4708N features on-chip protectors and standby switch.
Features
 
  • High power : supports total output of 30W+30W (VCC=13.2V, THD=30%, RL=4Ω)
  • Supports RL=2Ω (PO=30W when VCC=13.2V, THD=10%)
  • Designed for excellent sound quality (fL<10Hz, fH=130kHz)
  • NF capacitor-less
  • Any on time settable by external capacitor
  • Less pop noise
  • Standby switch circuit on chip (microprocessor supported)
  • Various protectors on chip (output-to-ground short/output-to-VCC short/load short/overvoltage/thermal shutdown circuit)
End Products
  • Car stereo
