tw 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).
FEATURES • 1W (8Ω) mono channel speaker output + stereo headphone driver • Digital controlled volume • Main volume: 32 steps/0dB ~ -90dB • Headphone volume: 8 steps/0dB ~ -10.
5dB • 2 microphone inputs, 1 microphone output • 2 stereo audio inputs, selected via I2C bus • Dual headphone output mode Integrated.
