2 / 24 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATING TABLE TPA741 SLOS316C – JUNE 2000 – REVISED JUNE 2004 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. AVAILABLE OPTIONS PACKAGED DEVICES TA MSOP SYMBOLIZATION SMALL OUTLINE(1) MSOP(2) (D) (DGN) –40 °C to 85°C TPA741D TPA741DGN AJD (1) In the D package, the maximum output power is thermally limited to 350 mW; 700-mW peaks can be driven, as long as the RMS value is less than 350 mW. (2) 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., TPA741DR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected BYPASS 2 I to a 0.1-µF to 2.2-µF capacitor when used as an audio amplifier. GND 7 GND is the ground connection. IN- 4 I IN- is the inverting input. IN- is typically used as the audio input terminal. IN+ 3 I IN+ is the noninverting input. IN+ is typically tied to the BYPASS terminal for SE operations. SHUTDOWN 1 I SHUTDOWN places the entire device in shutdown mode when held high. VDD 6 VDD is the supply voltage terminal. VO+ 5 O VO+ is the positive BTL output. VO- 8 O VO- is the negative BTL output. over operating free-air temperature range (unless otherwise noted)(1) UNIT VDD Supply voltage 6 v VI Input voltage –0.3 V to VDD +0.3 V Continuous total power dissipation Internally limited (see Dissipation Rating Table) TA Operating free-air temperature range –40 °C to 85°C TJ Operating junction temperature range –40 °C to 150°C Tstg Storage temperature range –65 °C to 150°C Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds 260 °C (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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. PACKAGE TA ≤ 25°C DERATING FACTOR TA = 70°C TA = 85°C D 725 mW 5.8 mW/ °C 464 mW 377 mW DGN 2.14 W(1) 17.1 mW/ °C 1.37 W 1.11 W (1) See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application Report (SLMA002), for more information on the PowerPAD package. The thermal data was measured on a PCB layout based on the information in the section entitled Texas Instruments Recommended Board for PowerPAD of that document. 2 |
