LA47202P Datasheet | SANYO

Overview .. Four-Channel BTL Power Amplifier for Car Audio Systems The LA47202P is a 4-channel BTL power amplifier IC developed for use in car audio applications. The LA47202P adopts a pure plementary output stage circuit structure with a v-pnp transistor for the high side and an npn transistor for the low side to provide both high output power and high quality sound. The LA47202P integrates all the functions required for car audio applications on the same chip, including a standby switch, a muting function, and a full plement of protection circuits. It also features a self diagnostics function. Functions - High output : PO max = 47W (typ.) (VCC = 14.4V, f = 1k Hz, JEITA max, RL = 4Ω) : PO max = 29W (typ.) (VCC = 14.4V, f = 1k Hz, THD = 10%, RL = 4Ω) : PO max = 22W (typ.) (VCC = 14.4V, f = 1k Hz, THD = 1%, RL = 4Ω) - Muting function incorporated (pin 22) - Built-in standby switch (pin 4) - Self diagnostics function incorporated (pin 25) : Output of both output offset detection, shorting to VCC or ground and load shorting signals - Electric mirror noise decrease - Full pliment of protection circuits (shorting to VCC, shorting to ground, load shorting, overvoltage, and thermal protection). - Improved oscillation stability Note 1 : Take care to avoid wrong connection. Otherwise, IC or equipment may suffer breakdown, damage, or deterioration. Note 2 : The protective circuit function is to avoid the abnormal state (wrong connection of the output) temporarily and does not guarantee that IC is not broken. These protective functions do not operate outside the operation guarantee range, and wrong connection of output may cause breakdown of IC. Note 3 : External parts, such as the anti-oscillation part, diode to prevent breakdown, may bee necessary depending on the set condition. Check their necessity for each set.
