INTEGRATED CIRCUITS DATA SHEET TDA1515BQ 24 W BTL or 2 x 12 W stereo car radio power amplifier Product specification File under Integrated Circuits, IC01 July 1994 Philips Semiconductors Product specification 24 W BTL or 2 x 12 W stereo car radio power amplifier 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. Special Features are: - 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 ponents - high reliability. The following currently required protections are incorporated in the circuit. These protections also have positive influence on reliability in the applications. - load dump protection - a.c. and d.c. short-circuit safe to ground up to VP = 18 V - thermal protection - speaker protection in bridge configuration - SOAR protection - outputs short-circuit safe to ground in BTL - reverse polarity safe.
