EMA1001-50MA08GRR - 1W Mono Audio Power Amplifier

Download the EMA1001-50MA08GRR datasheet PDF. This datasheet also covers the EMA1001 variant, as both devices belong to the same 1w mono audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The EMA1001 is an audio power amplifier primarily designed for portable communication applications such as mobile phones and portable multimedia players (PMP).

To an 8Ω BTL load, it can deliver 1 watt of continuous average power with less than 1% distortion (THD+N) from a 5VDC supply.

Key Features

  • Available in space-saving MSOP package Ultra low current shutdown mode BTL output driving capacitive loads Improved pop & click circuitry eliminating noises during turn-on and turn-off transitions.
  • 2.2 - 5.5V operation No output coupling capacitors, snubber networks or bootstrap capacitors required.
  • The EMA1001 is pin-compatible to National Semi’s LM4890 with a superior (THD+N). It does not require output coupling capacitors or bootstrap.
