TPA6102A2 50mW ULTRALOW VOLTAGE, FIXEDGAIN STEREO HEADPHONE AUDIO POWER AMPLIFIER SLOS324B − JUNE 2000 − REVISED SEPTEMBER 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 50-mW Stereo Output D Low Supply Current . . . 0.75 mA D Low Shutdown Current ...50 nA D Minimal External Components Required D Gain Set Internally to 14 dB D Pop Reduction Circuitry D Internal Mid-Rail Generation D Thermal and Short-Circuit Protection D Surface-Mount Packaging − MSOP − SOIC D 1.6-V to 3.6-V Supply Voltage Range description The TPA6102A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC package or an 8-pin MOSP package capable of delivering 50 mW of continuous RMS power per channel into 16- Ω loads. Amplifier gain is internally set to 14 dB (inverting) to save board space by eliminating six external resistors. The TPA6102A2 is optimized for battery applications because of its low-supply current, shutdown current, and THD+N. To obtain the low-supply voltage range, the TPA6102A2 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 6 7 5 2 VO1 VO2 VDD 3 8 1 4 IN 1− BYPASS SHUTDOWN VDD/4 CI 20 k Ω 100 k Ω CB CS Audio Input CI IN 2− VDD From Shutdown Control Circuit − + − + CC CC 100 k Ω 20 k Ω 100 k Ω 100 k Ω 1 2 3 4 8 7 6 5 BYPASS GND SHUTDOWN IN2− IN1− VO1 VDD VO2 D or DGK PACKAGE (TOP VIEW) Copyright 2004, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
