TDA1515BQ

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 W). At a supply voltage V_P = 14,4 V, an output power of 24 W can be delivered into a 4 W BTL (Bridge Tied Load), or, when used as stereo amplifier, it delivers 2 x 12 W into 2 W or 2 x 7 W into 4 W.

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 mA), 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.

• oad dump protection
• a.c. and d.c. short-circuit safe to ground up to V_P = 18 V
• thermal protection
• speaker protection in bridge configuration
• SOAR protection
• outputs short-circuit safe to ground in BTL
• reverse polarity safe.

Applications

• Portable AM/FM radio
• Clock radio
• Personal headphone radio
