EMA1003
1.2W Fully Differential Audio Power Amplifier with
Shutdown Select
General Description
The EMA1003 is a fully differential audio power amplifier
primarily designed for demanding applications in
mobile phones and other portable communication
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.
The EMA1003 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 transitions.
The EMA1003 is unity-gain stable and can be configured
by external gain-setting resistors.
