2 / 20 page TPA1517 6-W STEREO AUDIO POWER AMPLIFIER SLOS162B – MARCH 1997 – REVISED MARCH 2000 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Terminal Functions TERMINAL NAME DWP NO. NE NO. I/O DESCRIPTION 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 mode enable. 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 17 8 I M/SB is the mute/standby mode enable. When held at less than 2 V, this signal enables the TPA1517 for standby operation. When held between 3.4 V and 8.8 V, this signal enables the TPA1517 for mute operation. When held above 9.2 V, the TPA1517 operates normally. IN2 19 9 I IN2 in the audio input for channel 2. GND/HS 1, 10, 11, 20 10– 20 GND/HS are the ground and heatsink connections. All GND/HS terminals are connected directly to the mount pad for thermal-enhanced operation. absolute maximum ratings over operating free-air temperature range (unless otherwise noted)† Supply voltage, VCC 22 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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. NOTE 1: These devices have been classified as Class 1 ESD sensitive products per MIL-PRF-38535 Method 3015.7. Appropriate precautions should be taken to prevent serious damage to the device.
