File name la4598.pdf Ordering number: EN4087C Monolithic Linear IC LA4598 Two-channel Power Amplifier for Radio Cassette Players (No Heat Sink Needed during 9 V Operation) 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. Package Dimensions unit : mm 3113-SIP14HZ [LA4598] Functions . Thermal shutdown protector built in. . Standby switch built in. Features . No heat sink needed during 9 V operation . P = 2.9 W × 2 (V = 9 V, R = 3.2 , THD = 10%). . Less quiescent current. (V = 9 V, 20 mA, typ). . Operating voltage range: V op = 4.2 to 16 V.
