PRODUCTION DATA. TPA6111A2 SLOS313C – DECEMBER 2000 – REVISED MARCH 2016 TPA6111A2 150-mW Stereo Audio Power Amplifier 1 1 Features 1 • 150-mW Stereo Output • PC Power Supply Compatible – Fully Specified for 3.3-V and 5-V Operation – Operation to 2.5 V • Pop Reduction Circuitry • Internal Midrail Generation • Thermal and Short-Circuit Protection • Surface-Mount Packaging – PowerPAD™ MSOP – SOIC • Pin Compatible With TPA122, LM4880, and LM4881 (SOIC) 2 Applications • Smart Phones and Wireless Handsets • Portable Tablets • Notebook PCs and Docking Stations 3 Description The TPA6111A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC or an 8-pin PowerPAD MSOP package capable of delivering 150 mW of continuous RMS power per channel into 16- Ω loads. Amplifier gain is externally configured by means of two resistors per input channel and does not require external compensation for settings of 0 to 20 dB. THD+N, when driving a 16- Ω load from 5 V, is 0.03% at 1 kHz, and less than 1% across the audio band of 20 Hz to 20 kHz. For 32- Ω loads, the THD+N is reduced to less than 0.02% at 1 kHz, and is less than 1% across the audio band of 20 Hz to 20 kHz. For 10-k Ω loads, the THD+N performance is 0.005% at 1 kHz, and less than 0.5% across the audio band of 20 Hz to 20 kHz. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TPA6111A2 SOIC (8) 4.90 mm × 3.91 mm MSOP (8) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
