EMA1901
1.25W Mono Audio Power Amplifier
General Description
The EMA1901 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 1.25 watt of continuous average
power with less than 1% distortion (THD+N) from a 5VDC
supply. Typical THD+N is about 0.015% at 1Watt.
The EMA1901 is pin-compatible to National Semi’s LM4890
Micro-SMD package 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 EMA1901 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 EMA1901 is unity-gain stable
and can be configured by external gain-setting resistors.
EMP products are RoHS and Halogen free compliant.
