Description

The TPA4411MRTJT is a kind of TPA4411. The TPA4411 and TPA4411M are stereo headphone drivers designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The TPA4411 and TPA4411M are ideal for small portable electronics where size and cost are critical design parameters. The TPA4411 and TPA4411M are capable of driving 80 mW into a 16- load at 4.5 V. Both TPA4411 and TPA4411M have a fixed gain of 1.5 V/V and headphone outputs that have ±8-kV IEC ESD protection. The TPA4411 and TPA4411M have independent shutdown control for the right and left audio channels. The TPA4411 is available in a 2.18 mm * 2.18 mm WCSP and 4 mm * 4 mm Thin QFN packages. The TPA4411M is available in a 4 mm * 4 mm Thin QFN package. The TPA4411RTJ package is a thermally optimized PowerPAD™ package allowing the maximum amount of thermal dissipation and the TPA4411MRTJ is a thermally enhanced PowerPAD package designed to match competitive package footprints.

The features of TPA4411MRTJT are (1)space saving packages(20-Pin, 4 mm * 4 mm thin QFN: TPA4411 Thermally Optimized powerpad™ package; TPA4411M-thermally enhanced powerPAD™ package, 16-ball, 2.18 mm * 2.18 mm WCSP); (2)ground-referenced outputs eliminate DC-Bias voltages on headphone ground pin(no output DC-blocking capacitors: reduced board area; reduced component cost; improved THD+N performance; no degradation of low-frequency response due to output capacitors); (3)wide power supply range: 1.8 V to 4.5 V; (4)80-mW/Ch output power into 16- at 4.5 V; (5)independent right and left channel shutdown control; (6)short-circuit and thermal protection; (7)pop reduction circuitry.

The absolute maximum ratings of TPA4411MRTJT are (over operating free-air temperature range, TA = 25°C (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 operation 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 TPA4411MRTJT are (1)supply voltage, AVDD, PVDD: 0.3 V to 5.5 V; (2) VI(input voltage): 0.3 V to VDD + 0.3 V; (3)TJ(Operating junction temperature range): 40°C to 150°C; (4)Tstg (storage temperature range): 65°C to 85°C; (5)lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260°C; (6)output continuous total power dissipation: see dissipation rating table; (7)TA(operating free-air temperature range): 40°C to 85°C.
