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

GENERAL DESCRIPTION

The TDA1510AQ is a class-B integrated output amplifier encapsulated in a 13-lead single in-line (SlL) plastic power package. Developed primarily for car radio application, the device can also be used to drive low impedance loads (down to 1,6 Ω). With a supply voltage (VP) of 14,4 V, an output power of 24 W can be delivered into a 4 Ω Bridge Tied Load (BTL), or when used as a stereo amplifier, 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.

Features

• Flexibility − stereo as well as mono BTL
• Low offset voltage at the output (important for BTL)
• Load dump protection
• A.C. short-circuit-safe to ground
• Low number, small sized external components
• Internal limiting of bandwidth for high frequencies
• High output power
• Large useable gain variation
• Good ripple rejection
• Thermal protection
• Low stand-by current possibility
• High reliability.
