TPA112 150-mW STEREO AUDIO POWER AMPLIFIER SLOS212C – AUGUST 1998 – REVISED MARCH 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 150-mW Stereo Output D Wide Range of Supply Voltages – Fully Specified for 3.3 V and 5 V Operation – Operational From 2.5 V to 5.5 V D Thermal and Short-Circuit Protection D Surface Mount Packaging – PowerPAD ™ MSOP – SOIC D Standard Operational Amplifier Pinout description The TPA112 is a stereo audio power amplifier packaged in an 8-pin PowerPAD ™ MSOP package capable of delivering 150 mW of continuous RMS power per channel into 8- Ω loads. Amplifier gain is externally configured by means of two resistors per input channel and does not require external compensation for settings of 1 to 10. THD+N when driving an 8- Ω load from 5 V is 0.1% at 1 kHz, and less than 2% across the audio band of 20 Hz to 20 kHz. For 32- Ω loads, the THD+N is reduced to less than 0.06% 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 0.01% at 1 kHz, and less than 0.02% across the audio band of 20 Hz to 20 kHz. functional block diagram Short-Circuit Protection Over-Temperature Protection VDD 8 VDD IN1– IN1+ IN2– IN2+ 2 3 6 5 VO1 1 VO2 7 4 RF RF RF RI RI RI RI VDD/2 CI CI CI CI LIN– LIN+ RIN– RIN+ RF RO RO RC RC CC CC To Headphone Jack (See TPA152) Copyright © 2000, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
