TS4984 2 x 1W Stereo audio power amplifier with active low standby mode ■ Operating from VCC=2.2V to 5.5V ■ 1W output power per channel @ VCC=5V, THD+N=1%, RL=8Ω ■ 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 8Ω load @ 5V. An externally controlled standby mode control reduces the supply current to less than 10nA per channel.
