Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TDA8547 2 × 1 W BTL audio amplifier with output channel switching Preliminary specification File under Integrated Circuits, IC01 1997 Oct 07 Philips Semiconductors Preliminary specification.

General Description

APPLICATIONS • Telemunication equipment • Portable consumer products • Personal puters • Motor-driver (servo).

TDA8547 The TDA8547(T) is a two channel audio power amplifier for an output power of 2 × 1 W with an 8 Ω load at a 5 V supply.

The circuit contains two BTL amplifiers with a plementary PNP-NPN output stage and standby/mute logic.

Key Features

  • Selection between output channels.
  • 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.
