EUA6027A

EUA6027A 2-W Stereo Audio Power Amplifier with Selectable Gain and Shutdown DESCRIPTOIN The EUA6027A is a stereo audio speaker amplifier in a 20-pin TSSOP thermally enhanced package. Operating on a single 5V supply, EUA6027A 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.
