Two-channel Power Amplifier for Radio Cassette Players (No Heat
Sink Needed during9VOperation)
Overview
The LA4598 is a two-channel power IC that is intended for
use in portable audio equipment. Needing no heat sink during
9 V operation facilitates set design with a small footprint.
Functions
.
Thermal shutdown protector built in.
.
Standby switch built in.
Features
.
No heat sink needed during 9 V operation
.
PO = 2.9 W × 2(VCC =9 V, RL = 3.2 , THD = 10%).
.
Less quiescent current. (VCC = 9 V, 20 mA, typ).
.
Operating voltage range: VCC op = 4.2 to 16 V.
