TDA8547 Datasheet 2 X 0.7w Btl Audio Amplifier

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD TDA8547 LINEAR INTEGRATED CIRCUIT 2 × 0.

General Description

The UTC TDA8547 is a two channel audio power amplifier for an output power of 2 × 0.7W with a 16Ω load at a 5V supply.

At a low supply voltage of 3.3V an output power of 0.6W with an 8Ω load can be obtained.

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 the load.
  • Thermally protected.
  • ORDERI.
