■ 1.2W output power per channel @ V_CC = 5V,
THD+N = 1%, R_L = 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.
