EUA5212
2-W S tereo Audio Power Amplifier
with Four Selec table Gain S ettings
DS5212 Ver 1.5 Nov. 2004
DESCRIPTOIN
The EUA5212 is a stereo audio power amplifier. When
driving 1 W into 8-
speakers, the EUA5212 has less than
0.8% THD+N across its specified frequency range. Included
within this device is integrated depop circuitry that virtually
eliminates transients that cause noise in the speakers.
Amplifier gain is internally configured and controlled by way
of two terminals (GAIN0 and GAIN1). BTL gain settings of
6dB, 15.5dB, 21.5dB and 27.6dB are provided, while SE gain
is always configured as 0dB for headphone drive. An internal
input MUX allows two sets of stereo inputs to the
amplifier .The
LINE
HP/
terminal allows the user to select
which MUX input is active, regardless of whether the
amplifier is in SE or BTL mode. In notebook applications,
where internal speakers are driven as BTL and the line outputs
(often headphone drive) are required to be SE, the EUA5212
automatically switches
into SE mode when the
is activated, and this reduces the gain to 0dB.
The EUA5212 consumes only 6 mA of supply current during
normal operation.
