LA47202P Datasheet (Sanyo Semicon Device) - Monolithic Linear IC Four-Channel BTL Power Amplifier

LA47202P Description

of Operation 1. Standby switch function (pin 4) The pin 4 threshold voltage is set to about 3 VBE. The amplifier is turned ON at the application voltage of 3.0V or more and OFF at 0.5V or less. 2. Muting function (pin 22) When pin 22 is set to the ground potential, the LA47202P goes to the muted sta

Ordering number : ENA0508 Monolithic Linear IC LA47202P Overview www.DataSheet4U.com 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 complementary 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 require
