THD+N=1%, RL=8

Ω

■ 10nA standby current

■ 62dB PSRR @ 217Hz with grounded inputs

■ High SNR: 100dB(A) typ.

■ Near-zero pop & click

■ Available in QFN16 4x4 mm, 0.5mm pitch,

leadfree package

Description

The TS4984 has been designed for top of the

class stereo audio applications. Thanks to its

compact and power dissipation efficient QFN

package, it suits various applications.

With a BTL configuration, this Audio Power

Amplifier is capable of delivering 1W per channel

of continuous RMS output power into an 8

Ω load

@ 5V.

An externally controlled standby mode control

reduces the supply current to less than 10nA per

channel. The device also features an internal

thermal shutdown protection.

The gain of each channel can be configured by

external gain setting resistors.

Applications

■ Cellular mobile phones

■ Notebook computers & PDAs

■ LCD monitors & TVs

■ Portable audio devices
