EMA1001 Datasheet 1w Mono Audio Power Amplifier

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT/EMP 1W Mono Audio Power Amplifier General.

General Description

The EMA1001 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.

EMA1001 Key Specifications „ „ „ „ PSRR at 217Hz, VDD = 5V (Fig.

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.
