SLOS524B – JUNE 2008 – REVISED JUNE 2008 1.7-W/Ch Stereo Class-D Audio Amplifier with Dynamic Range Compression and AGC 23 • Filter-Free Class-D Architecture The TPA2016D2 is a stereo, filter-free Class-D audio power amplifier with volume control, dynamic range • 1.7 W/Ch Into 8 Ω at 5 V (10% THD+N) compression (DRC) and automatic gain control • 750 mW/Ch Into 8 Ω at 3.6 V (10% THD+N) (AGC). It is available in a 2.2 mm x 2.2 mm WCSP • Power Supply Range: 2.5 V to 5.5 V package. • Flexible Operation With/Without I2C The DRC/AGC function in the TPA2016D2 is • Programmable DRC/AGC Parameters programmable via a digital I2C interface. The DRC/AGC function can be configured to automatically • Digital I2C Volume Control prevent distortion of the audio signal and enhance • Selectable Gain from –28 dB to 30 dB in 1-dB quiet passages that are normally not heard. The Steps (when compression is used) DRC/AGC can also be configured to protect the • Selectable Attack, Release and Hold Times speaker from damage at high power levels and compress the dynamic range of music to fit within the • 4 Selectable Compression Ratios dynamic range of the speaker. The gain can be • Low Supply Current: 3.5 mA selected from –28 dB to +30 dB in 1-dB steps. The • Low Shutdown Current: 0.2 µA TPA2016D2 is capable of driving 1.7 W/Ch at 5 V or 750 mW/Ch at 3.6 V into 8 Ω load. The device • High PSRR: 80 dB features independent software shutdown controls for • Fast Start-up Time: 5 ms each channel and also provides thermal and short • AGC Enable/Disable Function circuit protection. • Limiter Enable/Disable Function In addition to these features, a fast start-up time and • Short-Circuit and Thermal Protection small package size make the TPA2016D2 an ideal choice for cellular handsets, PDAs and other portable • Space-Saving Package applications. – 2,2 mm × 2,2 mm Nano-Free™ WCSP (YZH) • Wireless or Cellular Handsets and PDAs • Portable Navigation Devices • Portable DVD Player • Notebook PCs • Portable Radio • Portable Games • Educational Toys • USB Speakers 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Nano-Free is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
