Description
TPA2017D2RTJT TI IC AMP AUDIO PWR 2.8W D 20WQFN RoHS
The TPA2017D2 (sometimes referred to as TPA2017) is a stereo, filter-free Class-D audio power amplifier with SmartGain™ dynamic range compression (DRC), automatic gain control (AGC), and noise gate. It is available in a 4 mm x 4mm QFN package.
SmartGain™ functions are configured to automatically prevent distortion of the audio signal and enhance quiet passages that are normally not heard. SmartGain™ is a combined AGC DRC and Limiter that protects the speaker from damage at high power levels and compress the dynamic range of voice or music to fit within the dynamic range of the speaker. SmartGain™ DRC, limiter, and noise gate functions can be enabled or disabled. The TPA2017D2 (TPA2017) is capable of driving 1.7 W/Ch at 4 V or 750mW/Ch at 3.6 V into 8 
load or 2.8 W/Ch at 5 V or 1.5 W/Ch at 3.6 V into 4 . The device features an enable pin and also provides thermal and short circuit protection.
In addition to these features, a fast start-up time and small package size make the TPA2017D2 (TPA2017) an ideal choice for Notebook PCs, PDAs and other portable applications.
