2 / 32 page TPA311 350-mW MONO AUDIO POWER AMPLIFIER SLOS207B – JANUARY 1998 – REVISED MARCH 2000 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 AVAILABLE OPTIONS PACKAGED DEVICES MSOP TA SMALL OUTLINE† (D) MSOP† (DGN) MSOP Symbolization –40 °C to 85°C TPA311D TPA311DGN AAB † The D and DGN packages are available taped and reeled. To order a taped and reeled part, add the suffix R to the part number (e.g., TPA311DR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION BYPASS 2 I BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected to a 0.1- µF to 1-µF capacitor when used as an audio amplifier. GND 7 GND is the ground connection. IN 4 I IN is the audio input terminal. SE/BTL 3 I When SE/BTL is held low, the TPA311 is in BTL mode. When SE/BTL is held high, the TPA311 is in SE mode. SHUTDOWN 1 I SHUTDOWN places the entire device in shutdown mode when held high (IDD = 60 µA, VDD = 5 V). VDD 6 VDD is the supply voltage terminal. VO+ 5 O VO+ is the positive output for BTL and SE modes. VO– 8 O VO– is the negative output in BTL mode and a high-impedance output in SE mode. absolute maximum ratings over operating free-air temperature range (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.
