EMA1002 Datasheet 1w Mono Audio Power Amplifier

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT/EMP General.

General Description

The EMA1002 is an audio power amplifier primarily designed for portable munication 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.

The EMA1002 is pin-patible to National Semi’s LM4890 with a superior (THD+N).

Key Features

  • a low-power consumption shutdown mode, and an internal thermal shutdown protection mechanism. Advanced pop & click circuitry is built in to eliminate noises that would otherwise occur during turn-on and turn-off transitions. The EMA1001 is unity-gain stable and can be configured by external gain-setting resistors.
  • PSRR at 217Hz, VDD = 5V (Fig. 1) Power Output at 5.0V & 1% THD Power Output at 2.6V & 1% THD Shutdown Current EMA1002 1W Mono Audio Power Ampl.
