1 Watt Audio Power Amplifier
PT2301
DESCRIPTION
The PT2301 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 volumes have 49 steps from +15dB ~ -90dB and all
the functions can be controlled via I2C bus. In the output section, the PT2301 is equipped with both
stereo headphone driver and mono speaker amp maximum output up to 1 watt.
The PT2301 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 PT2301 has two mode types for different purposes, A-type (Output
Capacitor-less) or B-type (Output with Capacitor).
