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.
