2 / 17 page www.ti.com DESCRIPTION (CONTINUED) ABSOLUTE MAXIMUM RATINGS TPA6112A2 SLOS342A – DECEMBER 2000 – REVISED SEPTEMBER 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. THD+N when driving an 16- Ω load from 5 V is 0.03% at 1 kHz, and less than 1% across the audio band of 20 Hz to 20 kHz. For 32- Ω loads, the THD+N is reduced to less than 0.02% at 1 kHz, and is less than 1% across the audio band of 20 Hz to 20 kHz. For 10-k Ω loads, the THD+N performance is 0.005% at 1 kHz, and less than 0.5% across the audio band of 20 Hz to 20 kHz. AVAILABLE OPTIONS PACKAGED DEVICE TA MSOP SYMBOLIZATION MSOP(1) -40 °C to 85°C TPA6112A2DGQ TI APD (1) The DGQ package isavailable in left-ended tape and reel only (e.g., TPA6112A2DGQR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO BYPASS 4 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 5 I GND is the ground connection. IN1- 2 I IN1- is the negative input for channel 1. IN1+ 3 I IN1+ is the positive input for channel 1. IN2- 8 I IN2- is the negative input for channel 2. IN2+ 7 I IN2+ is the positive input for channel 2. SHUTDOWN 6 I Puts the device in a low quiescent current mode when held high. VDD 10 I VDD is the supply voltage terminal. VO1 1 O VO1 is the audio output for channel 1. VO2 9 O VO2 is the audio output for channel 2. over operating free-air temperature (unless otherwise noted(1)) UNITS VDD Supply voltage 6 V VI Input voltage -0.3 V to VDD + 0.3 V Continuous total power dissipation internally limited 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 thoselisted under absolute maximum ratings may cause permanent damage to the device.These are stress ratings only, and functional operation of the device at theseor any other conditions beyond those indicated under recommended operatingconditions is not implied. Exposure to absolute-maximum-rated conditions forextended periods may affect device reliability. 2 |
