LA4631

Ordering number : ENN8177 SANYO Semiconductors DATA SHEET Monolithic Linear IC LA4631 Overview 5 W Two-Channel AF Power Amplifier for Audio Applications The LA4631 (5 W × 2 channels) is a single-ended power IC that has a pin arrangement similar to the LA4632 BTL power IC (10 W × 2 channels). The LA4631's pin compatibility makes it possible to share a common printed circuit board among a series of end products differentiated by power rank. (Note that the LA4632 is provided in an SIP-12H package, and that it is necessary to provide a hole for the LA4631 pin 13 if the same printed circuit board is to be shared. Note also that certain external components differ.) www.DataSheet4U.net Functions and Applications Two-channel power amplifier for audio applications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output current Allowable power dissipation Maximum junction temperature Operating temperature Storage temperature Symbol VCC max IO peak Pd max Tj max Topr Tstg With no input signal Per channel With an infinitely large heat sink Conditions Rated value 24 2 15 150 –20 to +75 –40 to +150 Unit V A W °C °C °C Operating Conditions at Ta = 25°C Parameter Recommended supply voltage Recommended load resistance range Allowable operating supply voltage range Symbol VCC RL op VCC op Conditions Rated value 14 4 5.5 to 22 Unit V Ω V *: VCC, RL, and the output level must be set for the size of the heat sink used so that the Pd max range is not exceede...
