Description
The TS488/9 is an enhancement of TS486/7 that
eliminates pop and click noise and reduces the
number of external passive components.
The TS488/9 is a dual audio power amplifier
capable of driving, in single-ended mode, either a
16
Ω
or a 32
Ω
stereo headset.
Capable of descending to low voltages, it delivers
up to 31mW per channel (into 16
Ω
loads) of
continuous average power with 0.1% THD+N in
the audio bandwidth from a 2.5V power supply.
An externally-controlled standby mode reduces
the supply current to 10nA (typ.). The unity gain
stable TS488/9 is configured by external gain-
setting resistors.
Applications
■
Headphone amplifier
■
Mobile phone, PDA, computer motherboard
■
High-end TV, portable audio player
