EMA1201
2W Stereo Audio Power Amplifier with Shutdown Mode
General Description
The EMA1201 is a stereo bridged audio power amplifier
capable of delivering 1.2W of continuous average
power into a 8Ω load or 1.7W into 4Ω with less than 1%
THD when powered by a 5V power supply. 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 EMA1201 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 EMA1201 is
unity-gain stable and can be configured by external
gain-setting resistors.
EMP products are Pb-free and RoHS compliant.
