TS4984IQT
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
DescriptionThe 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. The device also features an internal
thermal shutdown protection.
The gain of each channel can be configured by
external gain setting resistors.
