2 / 20 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATING TABLE RECOMMENDED OPERATING CONDITIONS TPA1517 SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007 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. Terminal Functions TERMINAL I/O DESCRIPTION DWP NE NAME NO. NO. IN1 2 1 I IN1 is the audio input for channel 1. SGND 4 2 I SGND is the input signal ground reference. SVRR 5 3 SVRR is the midrail bypass. OUT1 7, 8 4 O OUT1 is the audio output for channel 1. PGND 9, 12 5 PGND is the power ground reference. OUT2 13, 14 6 O OUT2 is the audio output for channel 2. VCC 16 7 I VCC is the supply voltage input. M/SB is the mute/standby mode enable. When held at less than 2 V, this signal enables the M/SB 17 8 I TPA1517 for standby operation. When held between 3.5 V and 8.2 V, this signal enables the TPA1517 for mute operation. When held above 9.3 V, the TPA1517 operates normally. IN2 19 9 I IN2 in the audio input for channel 2. 1, 10, GND/HS are the ground and heatsink connections. All GND/HS terminals are connected directly to GND/HS 10-20 11, 20 the mount pad for thermal-enhanced operation. over operating free-air temperature range (unless otherwise noted) UNIT VCC Supply voltage 22 V VI Input voltage (IN1, IN2) 22 V Internally limited Continuous total power dissipation (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 85°C PACKAGE TA ≤ 25°C DERATING FACTOR TA = 70°C TA = 85°C DWP(1) 2.94 W 23.5 mW/ °C 1.88 W 1.53 W NE(1) 2.85 W 22.8 mW/ °C 1.82 W 1.48 W (1) See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application Report (literature number 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 on page 33 of the before mentioned document.
