TDA8542AT - 2 x 1.5 W BTL audio amplifier

General Description

The TDA8542AT is a two channel audio power amplifier for an output power of 2 × 1.5 W with an 8 Ω load at a 6 V supply.

The circuit contains two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN output stage and standby/mute logic.

The TDA8542AT comes in a 20-pin SO package.

Key Features

  • Flexibility in use.
  • Few external components.
  • Low saturation voltage of output stage.
  • Gain can be fixed with external resistors.
  • Standby mode controlled by CMOS compatible levels.
  • Low standby current.
  • No switch-on/switch-off plops.
  • High supply voltage ripple rejection.
  • Protected against electrostatic discharge.
  • Outputs short-circuit safe to ground, VCC and across the load.
  • Thermally protected. QUIC.
