It is available in a 2.2 mm x 2.2 mm WCSP • 3.2 W/Ch Into 4 Ω at 5 V (10% THD+N) package. • 750 mW/Ch Into 8 Ω at 3.6 V (10% THD+N) The DRC/AGC function in the TPA2026D2 is • Power Supply Range: 2.5 V to 5.5 V programmable via a digital I2C interface. The DRC/AGC function can be configured to automatically • Flexible Operation With/Without I2C prevent distortion of the audio signal and enhance • Programmable DRC/AGC Parameters quiet passages that are normally not heard. The • Digital I2C Volume Control DRC/AGC can also be configured to protect the • Selectable Gain from 0 dB to 30 dB in 1-dB speaker from damage at high power levels and compress the dynamic range of music to fit within the Steps dynamic range of the speaker. The gain can be • Selectable Attack, Release and Hold Times selected from 0 dB to +30 dB in 1-dB steps. The • 4 Selectable Compression Ratios TPA2026D2 is capable of driving 3.2 W/Ch at 5 V into an 4- Ω load or 750 mW/Ch at 3.6 V into an 8-Ω • Low Supply Current: 3.5 mA load. The device features independent software • Low Shutdown Current: 0.2 mA shutdown controls for each channel and also provides • High PSRR: 80 dB thermal and short circuit protection. The TPA2026D2 • AGC Enable/Disable Function has faster AGC gain ramp during start-up than TPA2026D2. • 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 TPA2026D2 an ideal • Space-Saving Package choice for cellular handsets, PDAs, and other – 2,2 mm × 2,2 mm Nano-Free™ WCSP (YZH) portable applications. APPLICATIONS SIMPLIFIED APPLICATION DIAGRAM • 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 SmartGain, Nano-Free are trademarks of Texas Instruments. 3 All other trademarks are the property of their respective owners.
