Description :

Ordering number:ENN750F Monolithic Linear IC LA4440 6W 2-Channel, Bridge 19W typ Power Amplifier Features • Built-in 2 channels (dual) enabling use in stereo and bridge amplifier applications. Dual : 6W×2 (typ.) Bridge : 19W (typ.) • Minimun number of external parts required. • Small pop noise at the time of power supply ON/OFF and good starting balance. • Good ripple rejection : 46dB (typ.) • Good channel separation. • Small residual noise (Rg=0). • Low distortion over a wide range from low frequencies to high frequencies. • Easy to design radiator fin. • Built-in audio muting function. • Built-in protectors. a. Thermal protector b. Overvoltage, surge voltage protector c. Pin-to-pin short protector Package Dimensions unit:mm 3023A-SIP14H [LA4440] 37.0 30.0 4.5 15.0max 13.8 R1.7 0.8min 8.0 6.0 1 1.99 2.54 0.6 1.4 14 0.4 2.25 SANYO : SIP14H Specifications Absolute Maximum Ratings at Ta = 25˚C Parameter Maximum supply voltage Surge supply voltage Allowable power dissipation Termal resistance Operating temperature Storage temperature Symbol VCC max1 VCC max2 VCC(surge) Conditions Quiescent (t=30s) Operating t≤0.2s Tc=75˚C, See Pd max – Ta characteristic Junction-to-case Ratings 25 18 50 15 3 –20 to +75 –40 to +150 11.0 Unit V V V W ˚C/W ˚C ˚C Pd max θj-c Topr Tstg Recommended Operating Conditions at Ta = 25˚C Parameter Supply voltage Load resistance Symbol VCC RL Stereo Bridge Conditions Ratings 13.2 2 to 8 4 to 8 Unit V Ω Ω Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
