LA4708
Overview
The LA4708 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 capacitorless circuit, and crosstalk which
causes “muddy” sound has been reduced by improving both circuit and pattern layout. As a result, the LA4708 provides
powerful bass and clear treble. In addition, the LA4708 features on-chip protectors and standby switch. The LA4708 is
also pin-compatible with the LA4705NA (car stereo-use 17W two-channel power IC), and can be substituted for the
LA4705NA for higher power. (When the board is shared, pins 1 and 9 must be left open.)
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 capacitorless
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)
Monolithic Linear IC
For Car Stereos
20W 2-Channel BTL AF Power
Amplifier
Ordering number : EN5245B
