TDA1515BQ
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 components
• 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.
