TRA1309AP - Functional Speaker Driver

General Description

TRA1309AP is a speaker amplifier that can accept PWM signal and doesn’t need any external device for these input signals.

PWM input supports mainly for TRITAN’s PWM output.

The TRA1309AP contains advanced de-pop circuitry which eliminates pops during chip enable and disable.

Functional Speaker Driver TRA1309AP 1. General Descriptions TRA1309AP is a speaker amplifier that can accept PWM signal and doesn’t need any external device for these input signals. PWM input supports mainly for TRITAN’s PWM output. The TRA1309AP contains advanced de-pop circuitry which eliminates pops during chip enable and disable. The gain can be adjusted by connecting a resistor between RGAIN and SPKN to determine gain. Internal sound processing is added for better sound quality. 2.
