2 / 23 page TPA102 150-mW STEREO AUDIO POWER AMPLIFIER SLOS213C – AUGUST 1998 – REVISED MARCH 2000 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 AVAILABLE OPTIONS TA PACKAGED DEVICE MSOP TA MSOP† Symbolization –40 °C to 85°C TPA102DGN TI AAC † The DGN package is available in left-ended tape and reel only (e.g., TPA102DGNR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION BYPASS 1 I Tap to voltage divider for internal mid-supply bias supply. Connect to a 0.1 µF to 1 µF low ESR capacitor for best performance. GND 2 I GND is the ground connection. IN1– 8 I IN1– is the inverting input for channel 1. IN2– 4 I IN2– is the inverting input for channel 2. SHUTDOWN 3 I Puts the device in a low quiescent current mode when held high. VDD 6 I VDD is the supply voltage terminal. VO1 7 O VO1 is the audio output for channel 1. VO2 5 O VO2 is the audio output for channel 2. absolute maximum ratings over operating free-air temperature (unless otherwise noted)† Supply voltage, VDD 6 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
