3 / 24 page www.ti.com TPA2008D2 SLOS413C – JULY 2003 – REVISED MAY 2004 TERMINAL FUNCTIONS TERMINAL I/O DESCRIPTION NO. NAME AGND 12 - Analog ground BYPASS 22 I Tap to voltage divider for internal mid-supply bias generator used for internal analog reference. COSC 10 I A capacitor connected to this terminal sets the oscillation frequency in conjunction with ROSC. For proper operation, connect a 220-pF capacitor from COSC to ground. LINN 1 I Negative differential audio input for left channel LINP 2 I Positive differential audio input for left channel LOUTN 8 O Negative audio output for left channel LOUTP 5 O Positive audio output for left channel NC 15 I No connection PGNDL 6, 7 - Power ground for left channel H-bridge PGNDR 18, 19 - Power ground for right channel H-bridge PVDDL 4, 9 Power supply for left channel H-bridge PVDDR 16, 21 Power supply for right channel H-bridge RINN 24 I Positive differential audio input for right channel RINP 23 I Negative differential audio input for right channel ROSC 11 I A resistor connected to the ROSC terminal sets the oscillation frequency in conjunction with COSC. For proper operation, connect a 120-k Ω resistor from ROSC to ground. ROUTN 17 O Negative output for right channel ROUTP 20 O Positive output for right channel SHUTDOWN 3 I Places the amplifer in shutdown mode if a TTL logic low is placed on this terminal; normal operation if a TTL logic high is placed on this terminal. VDD 13 - Analog power supply VOLUME 14 I DC volume control for setting the gain on the internal amplifiers. The dc voltage range is 0 to VDD. Thermal Pad - - Connect to analog ground and the power grounds must be soldered down in all applications to properly secure device on the PCB. 3 |
