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 3Ω 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.
