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.

To save power consumption in the portable applications, the FAN7031 provides shutdown function.
