EUA6027
2-W Stereo Audio Power Amplifier
with Selectable Gain and Shutdown
DESCRIPTOIN
The EUA6027 is a stereo audio speaker amplifier in a 20-pin
TSSOP thermally enhanced package. Operating on a single 5V
supply, EUA6027 is capable of delivering 2W of output power
per channel into 3 loads with less than 1% THD+N.
Amplifier gain is internally configured and controlled by way of
two terminals (GAIN0 and GAIN1). Gain settings of 6 dB, 10 dB,
15.6 dB, and 21.6 dB (inverting) are provided. Internal gain
control requires few external components.
Other features include an active-low shutdown mode input and
thermal shutdown protection.
