3 / 49 page TPA0202 2-W STEREO AUDIO POWER AMPLIFIER SLOS205B – FEBRUARY 1998 – REVISED DECEMBER 2000 3 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION GND/HS 1, 12, 13, 24 Ground connection for circuitry, directly connected to thermal pad HP/LINE 16 I Input MUX control input, hold high to select LHP IN or RHP IN (5, 20), hold low to select LLINE IN or RLINE IN (4, 21) LBYPASS 6 Tap to voltage divider for left channel internal mid-supply bias LHP IN 5 I Left channel headphone input, selected when HP/LINE terminal (16) is held high LLINE IN 4 I Left channel line input, selected when HP/LINE terminal (16) is held low LOUT+ 3 O Left channel + output in BTL mode, + output in SE mode LOUT– 10 O Left channel – output in BTL mode, high-impedance state in SE mode LVDD 7 I Supply voltage input for left channel and for primary bias circuits MUTE IN 11 I Mute all amplifiers, hold low for normal operation, hold high to mute MUTE OUT 9 O Follows MUTE IN terminal (11), provides buffered output NC 17, 23 No internal connection RBYPASS 19 Tap to voltage divider for right channel internal mid–supply bias RHPIN 20 I Right channel headphone input, selected when HP/LINE terminal (16) is held high RLINEIN 21 I Right channel line input, selected when HP/LINE terminal (16) is held low ROUT+ 22 O Right channel + output in BTL mode, + output in SE mode ROUT– 15 O Right channel – output in BTL mode, high impedance state in SE mode RVDD 18 I Supply voltage input for right channel SE/BTL 14 I Hold low for BTL mode, hold high for SE mode SHUTDOWN 8 I Places entire IC in shutdown mode when held high, IDD = 5 µA TJ 2 O Sources a current proportional to the junction temperature. This terminal should be left unconnected during normal operation. For more information, see the junction temperature measurement section of this document. |
