TS4984FC

1.2W Stereo Audio Power Amplifier with

Active Low Standby Mode

■ Operating from VCC = 2.2V to 5.5V

■ 1.2W output power per channel @ VCC = 5V,

THD+N = 1%, RL = 8Ω

■ 10nA standby current

■ 62dB PSRR @ 217Hz with grounded inputs

■ High SNR: 106dB(A) typ.

■ Near-zero pop & click

■ Available in a 15-bump flip-chip (lead-free)

Description

The TS4984 has been designed for top-class

stereo audio applications. Thanks to its compact

and power dissipation efficient flip-chip package, it

suits various applications.

With a output BTL configuration, this audio power

amplifier is capable of delivering 1.2W per

channel of continuous RMS output power into an

8Ω load @ 5V.

An externally-controlled standby mode 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.
