EMA1002 - 1W Mono Audio Power Amplifier

General Description

The EMA1002 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

  • 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.

ESMT/EMP General Description The EMA1002 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. The EMA1002 is pin-compatible to National Semi’s LM4890 with a superior (THD+N). It does not require output coupling capacitors or bootstrap capacitors, and is ideal for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The EMA1002 features a low-power consumption shutdown mode, and an internal thermal shutdown protection mechanism.
