Overview
Ordering number : ENA1783A LA4708N Monolithic Linear IC 20W 2-channel BTL AF Power Amplifier for Car Stereo http://onsemi.
com 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) Specifications Maximum Ratings at Ta = 25C Parameter Symbol Conditions Maximum supply voltage VCC max 1 No signal, t = 60s VCC max 2 Surge supply voltage Maximum output current Allowable power dissipation VCC surge IO peak Pd max t 0.
