6 / 29 page www.ti.com TPA3008D2 SLOS435A – MAY 2004 – REVISED JULY 2004 TERMINAL FUNCTIONS PIN NAME PIN NUMBER I/O DESCRIPTION AGND 26, 30 - Analog ground for digital/analog cells in core AVCC 33 - High-voltage analog power supply, not connected internally to PVCCR or PVCCL 5-V Regulated output for use by internal cells and GAIN0, GAIN1 pins only. Not AVDD 29 O specified for driving other external circuitry. AVDDREF 7 O 5-V Reference output—connect to gain setting resistor or directly to GAIN0, GAIN1. BSLN 13 - Bootstrap I/O for left channel, negative high-side FET BSLP 24 - Bootstrap I/O for left channel, positive high-side FET BSRN 48 - Bootstrap I/O for right channel, negative high-side FET BSRP 37 - Bootstrap I/O for right channel, positive high-side FET COSC 28 I/O I/O for charge/discharging currents onto capacitor for ramp generator. Short-circuit detect fault output. FAULT = high, short-circuit detected. FAULT 11 O FAULT = low, normal operation. Status is reset when power is cycled or SHUTDOWN is cycled. GAIN0 9 I Gain select least significant bit. TTL logic levels with compliance to AVDD. GAIN1 10 I Gain select most significant bit. TTL logic levels with compliance to AVDD. LINN 6 I Negative audio input for left channel LINP 5 I Positive audio input for left channel LOUTN 16, 17 O Class-D 1/2-H-bridge negative output for left channel LOUTP 20, 21 O Class-D 1/2-H-bridge positive output for left channel 8, 12, 31, 32, NC - No internal connection 34, 35 PGNDL 18, 19 - Power ground for left channel H-bridge PGNDR 42, 43 - Power ground for right channel H-bridge Power supply for left channel H-bridge (internally connected to pins 22 and 23), not PVCCL 14, 15 - connected to PVCCR or AVCC. Power supply for left channel H-bridge (internally connected to pins 14 and 15), not PVCCL 22, 23 - connected to PVCCR or AVCC. Power supply for right channel H-bridge (internally connected to pins 46 and 47), PVCCR 38, 39 - not connected to PVCCL or AVCC. Power supply for right channel H-bridge (internally connected to pins 38 and 39), PVCCR 46, 47 - not connected to PVCCL or AVCC. RINP 3 I Positive audio input for right channel RINN 2 I Negative audio input for right channel ROSC 27 I/O I/O current setting resistor for ramp generator. ROUTN 44, 45 O Class-D 1/2-H-bridge negative output for right channel ROUTP 40, 41 O Class-D 1/2-H-bridge positive output for right channel Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with SHUTDOWN 1 I compliance to VCC. VCLAMPL 25 - Internally generated voltage supply for left channel bootstrap capacitors. VCLAMPR 36 - Internally generated voltage supply for right channel bootstrap capacitors. V2P5 4 O 2.5-V Reference for analog cells. Connect to AGND and PGND—should be the center point for both grounds. Internal Thermal Pad - - resistive connection to AGND. 6 |
