EMA1201
EMA1201 is 2W Stereo Audio Power Amplifier manufactured by Elite Semiconductor Microelectronics Technology.
ESMT/EMP
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 Ro HS pliant.
