Keywords:stmicroelectronics? ts483? stereo headphone amplifier?

The TS482 stereo headphone amplifier from STMicroelectronics delivers 110dB SNR and a power supply ripple rejection of 85dB (5V), making them suitable for use in high-end home A/V systems, PC sound cards, and CD-ROM drives.

The device also offers crosstalk immunity of 100dB at 1kHz and 80dB across the audible spectrum of 20Hz to 20kHz, and is designed to reduce switch on/off clicks.

It operates from a supply voltage of 2V to 5.5V and provides up to 100mW (5.5V) output per channel into a 16-ohm load with a maximum distortion of 0.1 percent THD+N. The TS482 is able to drive 16-ohm or 32-ohm headphones and operates at a temperature range of -400C to 850C.

Shipped in either a MiniSO-8 or SO-8 package, the device has rail-to-rail I/Os and is stable at unity gain, and can be configured using external gain-setting resistors.
