Description

The TPA3100D2RGZT belongs to the TPA3100D2 family, which is a 20-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. The TPA3100D2 can drive stereo speakers as low as 4 . The high efficiency of the TPA3100D2, 92%, eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB. The outputs are fully protected against shorts to GND, VCC, and output-to-output shorts with an auto recovery feature and monitor output.

The features of TPA3100D2RGZT are (1)20-W/ch into an 8- load from a 18-V supply; (2)10-W/ch into an 8- load from a 12-V supply; (3)15-W/ch into an 4- load from a 12-V supply; (4)operates from 10 V to 26 V; (5)92% efficient class-D operation eliminates need for heat sinks; (6)four selectable, fixed gain settings; (7)differential inputs; (8)thermal and short-circuit protection with auto recovery feature; (9)clock output for synchronization with multiple class-D devices; (10)surface mount 7 mm * 7 mm, 48-pin QFN package; (11)surface mount 7 mm * 7 mm, 48-pin TQFP package.

The absolute maximum ratings over operating free-air temperature range of TPA3100D2RGZT (unless otherwise noted)( 1: Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operations of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.)) of TPA3100D2 are (1) VCC(supply voltage, AVCC, PVCC): 0.3 V to 30 V; (2)TA (operating free-air temperature range): -40°C to 85°C; (3)TJ (operating junction temperature range(2: The TPA3100D2 incorporates an exposed thermal pad on the underside of the chip. This acts as a heatsink, and it must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in the device going into thermal protection shutdown.

See TI technical briefs SLMA002 for more information about using the TQFP thermal pad.)): -40°C to 150°C; (4) Tstg (storage temperature range): 65°C to 150°C; (5)lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260°C; (6)RLoad(load resistance): 3.2 minimum; (7)electrostatic discharge: ±2 kV(Human body model (3: in accordance with JEDEC standard 22, test method A114-B.)
