TPA6101A2 50mW ULTRALOW VOLTAGE, FIXEDGAIN STEREO HEADPHONE AUDIO POWER AMPLIFIER SLOS331C − AUGUST 2000 − REVISED MARCH 2007 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Minimal External Components Required D 1.6-V to 3.6-V Supply Voltage Range D 50-mW Stereo Output D Low Supply Current . . . 0.75 mA D Low Shutdown Current ...50 nA D Gain Set Internally to 2 dB D Pop Reduction Circuitry D Internal Mid-Rail Generation D Thermal and Short-Circuit Protection D Surface-Mount Packaging − 3-mm y 5-mm MSOP Package (DGN) − 5-mm y 6-mm SOIC Package (D) − 2,5-mm y 2,5-mm MicroStar JuniorE BGA Package (ZQY) description The TPA6101A2 is a stereo audio power amplifier packaged in an 8-pin SOIC package, an 8-pin MSOP package, or a 15-ball BGA package, capable of delivering 50 mW of continuous RMS power per channel into 16- Ω loads. Amplifier gain is internally set to 2 dB (inverting) to save board space by eliminating six external resistors. The TPA6101A2 is optimized for battery applications because of its low supply current, shutdown current, and THD+N. To obtain the low-supply-voltage range, the TPA6101A2 biases BYPASS to VDD/4. When driving a 16- Ω load with 40-mW output power from 3.3 V, THD+N is 0.08% at 1 kHz, and less than 0.2% across the audio band of 20 Hz to 20 kHz. For 30 mW into 32- Ω loads, the THD+N is reduced to less than 0.06% at 1 kHz, and is less than 0.3% across the audio band of 20 Hz to 20 kHz. typical application circuit Audio Input Bias Control VO1 VO2 VDD IN 1− BYPASS SHUTDOWN VDD/4 CI 80 k Ω RF 80 k Ω CB CS Audio Input CI IN 2− VDD From Shutdown Control Circuit − + − + CC CC 80 k Ω RI 80 k Ω RF 80 k Ω NOTE: All internal resistor values are ±20%. 80 k Ω RI MicroStar BGA is a trademark of Texas Instruments.
