2 / 23 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATING TABLE RECOMMENDED OPERATING CONDITIONS TPA4861 SLOS163C – SEPTEMBER 1996 – 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 DEVICE TA SMALL OUTLINE(1) (D) –40 °C to 85°C TPA4861D (1) The D package is available tape and reeled. To order a tape and reeled part, add the suffix R to the part number (e.g., TPA4861DR). 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 – 1.0-µF capacitor when used as an audio power 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 (IDD ~ 0.6 µA). VO1 5 O VO1 is the positive BTL output. VO2 8 O VO2 is the negative BTL output. VDD 6 VDD is the supply voltage terminal. 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.
