LA4708N
Overview
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 = 4)
Supports RL = 2 (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)
