The TPA4411RTJ from Texas Instruments is a stereo headphone driver designed for applications where reduced component count and cost are critical. This amplifier is capable of delivering 80 mW per channel into a 16-ohm load at 4.5 V.
Key electrical characteristics include a wide power supply range from 1.8 V to 4.5 V and a fixed gain of 1.5 V/V. The device features ground-referenced outputs, eliminating the need for output DC-blocking capacitors, which reduces board area and component cost. It also includes independent shutdown control for the right and left audio channels, short-circuit and thermal protection, and a pop reduction circuit.
The TPA4411RTJ is available in space-saving packages such as a 20-pin, 4 mm x 4 mm Thin QFN and a 16-ball, 2.18 mm x 2.18 mm WCSP. The operating temperature range is -40°C to 85°C.
Applications for this headphone amplifier include notebook computers, smartphones, cellular phones, PDAs, and portable media players like CD/MP3 players.
The supply voltage range is 1.8 V to 4.5 V.
The TPA4411RTJ is available in WQFN (20-pin Thin QFN, 4 mm × 4 mm), DSBGA (16-ball WCSP, 2.18 mm × 2.18 mm), and other surface-mount packages.
The operating temperature range is -40°C to 85°C.
The output power is 80 mW per channel into a 16 Ω load at 4.5 V.
The fixed gain is 1.5 V/V.
The device provides ±8 kV IEC ESD protection on the headphone outputs.
