FAN7031 - 2W Stereo Power Amplifier

General Description

The FAN7031 is a dual fully differential power amplifier in a 20-pin TSSOP-EP thermally enhanced package.

When delivering 1.85W of continuous RMS power into 4Ω speaker at 5V supply, the FAN7031 has less than 1% of THD+N over the entire audible frequency range, 20Hz to 20kHz.

Key Features

  • 1.85WRMS and 2.45WRMS Power Per Each Channel Into 4Ω Load With Less Than 1% and 10% THD+N, Respectively.
  • Selectable Gain Via Internal Gain Control Circuit Which Eliminates External Gain Setting Resistors : 6dB, 10.3dB, 15.6dB, 21.6dB(Select).
  • Low Quiescent Current : Typical 5.5mA@5V.
  • Low Shutdown Current : Typical 0.04µA@5V.
  • Fully Differential Input, Which Immunes the Common Mode Noise.
  • Stereo Headphone Drive.
  • Active Low Shutdown Lo.
