Preliminary
Monolithic Linear IC
LA4728
2-Channel BTL Power Amplifier (35 W+35 W)
with Standby Switch for Car Stereos
Overview
The LA4728 is a BTL two-channel power IC for car
audios 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 LA4728 provides powerful bass and clear treble.
Features
⋅ High power: supports total output of 35 W+35 W. [EIAJ
power] (VCC=14.4 V, THD=30 %, RL=4 Ω)
⋅ Less pop noise.
⋅ Designed for excellent sound quality.
(fL<10 Hz, fH=130 kHz)
⋅ Any rise time settable by an external capacitor.
⋅ Standby switch circuit on chip. (microcontroller support-
ed)
⋅ Various protectors on chip.
(output-to-ground short/ output-to-VCC short/ load
short/ overvoltage/ thermal shutdown circuit)
⋅ The LA4728 is pin-compatible with the LA4725.
