2 / 28 page www.ti.com ABSOLUTE MAXIMUM RATINGS TPA721 SLOS231E – NOVEMBER 1998 – REVISED JUNE 2004 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. AVAILABLE OPTIONS PACKAGED DEVICES MSOP TA SMALL OUTLINE(1) MSOP(2) SYMBOLIZATION (D) (DGN) –40 °C to 85°C TPA721D TPA721DGN ABC (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., TPA301DR). 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 to a BYPASS 2 I 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. 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. 2 |
