General Description: The TDA1515BQ is a monolithic integrated class-B output amplifier in a 13-lead single in-line (SIL) plastic power  package. The device is primarily developed for car radio applications, and also to drive low-impedance loads (down to  1,6 Ω). At a supply voltage VP = 14,4 V, an output power of 24 W can be delivered into a 4 Ω BTL (Bridge Tied Load),  or, when used as stereo amplifier, it delivers 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω. Features: flexibility in use − mono BTL as well as stereo high output power low offset voltage at the output (important for BTL) large usable gain variation very good ripple rejection internal limited bandwidth for high frequencies low stand-by current possibility (typ. 1 µA), to simplify required switches; TTL drive possible low number and small sized external components high reliability. The following currently required protections are incorporated in the circuit. These protections also have posi...
