3 / 25 page www.ti.com TPA6010A4 SLOS268B – JUNE 2000 – REVISED AUGUST 2004 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. AVAILABLE OPTIONS PACKAGED DEVICE TA TSSOP(1) (PWP) -40 °C to 85°C TPA6010A4PWP (1) The PWP package is available taped and reeled. To order a taped and reeled part, add the suffix R to the part number (e.g., TPA6010A4PWPR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. BBENABLE is the bass boost control input. When this terminal is held high, the extra bass from the bass BBENABLE 3 I boost circuitry is added to the output signal. When this terminal is held low, no extra bass is added. BBIN 21 I BBIN is the buffered input to the power amplifier from the bass boost circuitry. BBOUT is the bass boost output. A low pass filter must be placed from BBOUT to BBIN to select the low BBOUT 20 O frequencies to be boosted. BYPASS 4 Tap to voltage divider for internal midsupply bias generator If a 47-nF capacitor is attached, the TPA6010A4 generates an internal clock. An external clock can CLK 27 I override the internal clock input to this terminal. The gain of the dockout buffer is adjustable from -52 dB to 8 dB to LDOCKOUT and RDOCKOUT, and is BUFFGAIN 24 I set by a dc voltage from 0 V to 3.54 V. When the dc level is over 3.54 V, the device is muted. GND 1, 15 Ground connection for circuitry. Connected to thermal pad. HP/LINE 13 I MUX control input, hold high to select LHPIN or RHPIN, hold low to select LLINEIN or RLINEIN. LHPIN 6 I Left channel headphone input, selected when HP/LINE is held high LIN 5 I Common left input for fully differential input. AC ground for single-ended inputs LLINEIN 7 I Left channel line negative input, selected when HP/LINE is held low LDOCKOUT is the buffered output of LLINEIN or LHPIN. Use BUFFGAIN for volume adjustment of this LDOCKOUT 26 O pin. LOUT+ 28 O Left channel positive output in BTL mode and positive output in SE mode LOUT- 2 O Left channel negative output in BTL mode and high-impedance in SE mode The input for PC Beep mode. PC-BEEP is enabled when a > 1.5-V (peak-to-peak) square wave is input to PC-BEEP 8 I PC-BEEP. AC ground if use is not desired. PVDD 19, 25 I Power supply for output stage RHPIN 10 I Right channel headphone input, selected when HP/LINE is held high RIN 11 I Common right input for fully differential input. AC ground for single-ended inputs RLINEIN 9 I Right channel line input, selected when HP/LINE is held low RDOCKOUT is the buffered output of RLINEIN or RHPIN. Use BUFFGAIN for volume adjustment of this RDOCKOUT 18 O pin. ROUT+ 16 O Right channel positive output in BTL mode and positive output in SE mode ROUT- 14 O Right channel negative output in BTL mode and high-impedance in SE mode Output MUX control. When this terminal is high, SE outputs are selected. When this terminal is low, the SE/BTL 17 I BTL outputs are selected. SHUTDOWN 12 I When held low, this terminal places the entire device, except PC-BEEP detect circuitry, in shutdown mode. VDD 22 I Analog VDD input supply. This terminal needs to be isolated from PVDD to achieve highest performance. VOLUME detects the dc level at the terminal and sets the gain for 31 discrete steps covering a range of 20 VOLUME 23 I dB to -40 dB for dc levels of 0.15 V to 3.54. When the dc level is over 3.54 V, the device is muted. Connect to GND. The pad must be soldered down in all applications in order to properly secure the device Thermal Pad to the PCB. 3 |
