Datasheet Summary
Functional Speaker Driver
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. Features z Accept PWM and doesn’t need any external devices for these input signals. z Mute function z Wide operation voltage : 2.4V~5.5V z sound processing for better sound quality z Auto power ON/OFF z...
