3 / 13 page TPA2001D2 1-W FILTERLESS STEREO CLASS-D AUDIO POWER AMPLIFIER SLOS292A – MARCH 2000 – REVISED APRIL 2000 3 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Terminal Function TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION AGND 6 – Analog ground BYPASS 22 I Tap to voltage divider for internal midsupply bias generator used for analog reference. COSC 7 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. GAIN0 3 I Bit 0 of gain control (TTL logic level) GAIN1 15 I Bit 1 of gain control (TTL logic level) LINN 5 I Left channel negative differential audio input LINP 20 I Left channel positive differential audio input LOUTN 2 O Left channel negative audio output LOUTP 23 O Left channel positive audio output PGND 1, 24 – Power ground for left channel H-bridge PGND 12, 13 – Power ground for right channel H-bridge PV 4, 21 – Power supply for left channel H-bridge PVDD 9, 16 – Power supply for right channel H-bridge RINN 8 I Right channel negative differential audio input RINP 17 I Right channel positive differential audio input ROSC 18 I A resistor connected to this terminal sets the oscillation frequency in conjunction with COSC. For proper operation, connect a 120 k Ω resistor from ROSC to ground. ROUTN 11 O Right channel negative audio output ROUTP 14 O Right channel positive output SHUTDOWN 10 I Places the amplifier 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.
