Eutech Microelectronics EUA5312

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. In notebook applications, where internal speakers are driven as BTL and the line outputs (often headphone drive) are required to be SE, the EUA5312 automatically switches into SE mode when the SE/ BTL input is activated, and this reduces the gain to 4.1 dB.

FEATURES

z z z z z z z z z z DESCRIPTOIN The EUA5312 is a stereo audio power amplifier. 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 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 amplifier .The HP/LINE terminal allows the user to select which MUX input is active, regardless of whether the amplifier is in SE or BTL mode. The EUA5312 consumes only 6mA of supply current during normal operation. 2W per Channel Output Power Into 3-Ω Load Internal Gain Control, Which Eliminates External Gain-Setting Components Input MUX Select Terminal PC-Beep Input Depop Circuitry Integrated Two Input Modes Allowable with Single-Ended or Fully Differential Input Low Supply Current...
