1W Audio Power Integration Amplifier

PT2307

DESCRIPTION

The PT2307 is an integration audio power amplifier IC utilizing advanced CMOS technology.

Supports 2 mono MIC input and 2 stereo line input, input gain of each amp can be set individually to

meet customers’ needs. Built-in digital controlled volume has 32 steps from 0dB ~ -90dB, the

headphone volume control has 8 steps ranging from 0dB ~ -10.5dB which can be further attenuate

from the main volume. All functions can be controlled via I²C bus. In the output section, the PT2307 is

equipped with both stereo headphone driver and mono speaker amp maximum output up to 1 watt.

The PT2307 also equipped “Energy Save” power management systems; user can turn off the unused

portion to minimize total power consumption for extended battery endurance. For different applications,

the headphone section of the PT2307 has two mode types for different purposes, A-type (Output

Capacitor-less) or B-type (Output with Capacitor).
