24 W BTL or 2 x 12 W stereo car radio power amplifier

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 stereohigh output powerlow offset voltage at the output (important for BTL)large usable gain variationvery good ripple rejectioninternal limited bandwidth for high frequencieslow stand-by current possibility (typ. 1 µA), to simplify required switches; TTL drive possiblelow number and small sized external componentshigh reliability.The following currently required protections are incorporated in the circuit. These protections also have positive influence on reliability in the applications.lo…
