LA4450 Overview The LA4450 is a single package 2-channel power Amplifier that supports an operating voltage of 26V. It is particularly well suited for use as the bus and track power IC in car stereo applications. Additionally, since the LA4450 can drive 4 loads, it can be used effectively in high-power high-end products. Furthermore, since it supports a high operating voltage and has low distortion, it is also optimal for use in TV and home audio products. Features Two channels in a single package PO = 12W2 (VCC = 26.4V, RL = 8, THD = 10%) PO = 20W2 (VCC = 26.4V, RL = 4, THD = 10%) Can drive 4 speakers Built-in standby switch Minimizes impulse noises Functions Standby switch (active on high (+5V) input) On-chip impulse noise protection circuit On-chip thermal protection circuit On-chip overvoltage and surge protection circuits Specifications Maximum Ratings at Ta = 25 C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max Rg = 0 (no signal) 37 V Maximum output current IO peak 4A Allowable power dissipation Pd max Infinite heat sink* 25 W Operating temperature Topr 35 to 80 C Storage temperature Tstg 40 to 150 C Note : * Set VCC and RL within ranges that do not cause Pd max to exceed 25W. (When VCC is 37V, RL should be 6 or larger and when VCC is 35V, RL should be 4 or larger.) Operating Conditions at Ta = 25 C Parameter Symbol Conditions Ratings Unit Recommended supply voltage VCC 26.4 V Recommended load resistance RL 8 Operating supply voltage range VCC op 10 to 30 V Ordering number : EN4090E Monolithic Linear IC 2-Channel, 26V, Power Amplifier for Bus and Track in Car Stereo Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability. SIP14 36.8x13.8 / SIP14H |
