EMA1003 Datasheet 1.2w Fully Differential Audio Power Amplifier

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT/EMP EMA1003 1.2W Fully Differential Audio Power Amplifier with Shutdown.

General Description

The EMA1003 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications.

It is capable of delivering 1.2 watt of continuous average power to an 8Ω　BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

The EMA1003 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

Key Features

  • a low-power consumption shutdown mode. To facilitate this, shutdown may be enabled by either logic high or low depending on mode selection. Driving the shutdown mode pin either high or low enables the shutdown select pin to be driven in a likewise manner to enable Shutdown. Additionally, the EMA1003 features an internal thermal shutdown protection mechanism. The EMA1003 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transit.
