Preliminary
EMA2217
2-W STEREO AUDIO POWER AMPLIFIER
WITH FOUR SELECTABLE GAIN SETTINGS
GENERAL DESCRIPTION
The EMA2217 is a stereo audio power amplifier in a
20-pin TSSOP thermally enhanced package
capable of driving 2W of continuous RMS power per
channel into 4Ω loads. Internal gain control
minimizes the number of external components
needed, simplifying the design, and freeing up
board space for other features. Amplifier gain is
internally configured and controlled by way of two
terminals (G0 and G1). Gain settings of 6 dB, 10 dB,
15.6 dB, and 21.6 dB are provided. EMP products are
Pb-free and RoHS compliant.
FEATURES
.Internal Gain control Which Eliminates External
Gain-Setting Resistors
.Fully Differential Configuration
.Low Supply Current (6mA Typical)
.De-pop Citcuitry
APPLICATIONS
.Notebook Computers, PDAs, and Other Portable
Audio devices
