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 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.

50 W high performance hi-fi amplifier

GENERAL DESCRIPTION

The TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment). The circuit is totally protected, the two output transistors both having thermal and SOAR protection (see Fig.3). The circuit also has a mute function that can be arranged for a period after power-on with a delay time fixed by external components. The device is intended for symmetrical power supplies but an asymmetrical supply may also be used.

Features

• High output power
• Low harmonic distortion
• Low intermodulation distortion
• Low offset voltage
• Good ripple rejection
• Mute/stand-by facilities
• Thermal protection
• Protected against electrostatic discharge
• No switch-on or switch-off clicks
• Very low thermal resistance
• Safe Operating Area (SOAR) protection.
