PA6204 - 1.7-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

General Description

The UTC PA6204 is a mono fully-differential audio amplifier, capable of delivering 1.7W of continuous average power to an 8-Ω BTL load with less than 10% distortion from a 5V power supply.

Key Features

  • 1.7W into 8Ω from a 5-V supply at THD=10% (Typ. ).
  • 2.5V-5.5V operation.
  • Low supply current: 4mA typ at 5V.
  • Ultra low current shutdown mode.
  • Only three external components - Improved PSRR (-80dB) for direct battery operation - Fully differential design reduces RF rectification - -63dB CMRR eliminates two input coupling capacitors.
  • Fast startup with minimal pop.
