EUA5202
2-W Stereo Audio Power Amplifier
with Mute
DESCRIPTION
The EUA5202 is a stereo audio power amplifier that
delivering 2W of continuous RMS power per channel
into 3-Ω loads. When driving 1W into 8-Ω speakers, the
EUA5202 has less than 0.04% THD+N across its
specified frequency range. Included within this device is
integrated de-pop circuitry that virtually eliminates
transients that cause noise in the speakers.
Amplifier gain is externally configured by means of two
resistors per input channel and does not require external
compensation for settings of 2 to 20 in BTL mode (1 to
10 in SE mode). An internal input MUX allows two sets
of stereo inputs to the amplifier. In notebook
applications, where internal speakers are driven as BTL
and the line (often headphone drive) outputs are required
to be SE, the EUA5202 automatically switches into SE
mode when the SE/BTL inputs is activated. Consume
only 7mA of supply current during normal operation,
and the EUA5202 also features a shutdown function for
power sensitive applications, holding the supply current
at 1µA.
