2-W Stereo Audio Power Amplifier

with Four Selectable Gain Settings

FEATURES

DESCRIPTOIN

The EUA5312 is a stereo audio power amplifier. When

driving 1 W into 8–Ω speakers, the EUA5312 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.

Depop Circuitry Integrated

Amplifier gain is internally configured and controlled by way

of two terminals (GAIN0 and GAIN1). BTL gain settings of 6

dB, 10 dB, 15.6 dB, and 21.6 dB are provided, while SE

gain is always configured as 4.1 dB for headphone drive. An

internal input MUX allows two sets of stereo inputs to the

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 EUA5312

RoHS Compliant and 100% Lead (Pb)-Free

automatically switches into SE mode when the

input

SE/BTL

is activated, and this reduces the gain to 4.1 dB.

APPLICATIONS

The EUA5312 consumes only 6mA of supply current during

normal operation.
