DESCRIPTION
The TS486/7 is a dual audio power amplifier capa-
ble of driving, in single-ended mode, either a 16 or
a 32Ω stereo headset.
Capable of descending to low voltages, it delivers
up to 90mW per channel (into 16Ω loads) of con-
tinuous average power with 0.3% THD+N in the
audio bandwitdth from a 5V power supply.
An externally-controlled standby mode reduces
the supply current to 10nA (typ.). The unity gain
stable TS486/7 can be configured by external
gain-setting resistors or used in a fixed gain ver-
sion.
APPLICATIONS
s Headphone Amplifier
s Mobile phone, PDA, computer motherboard
s High end TV, portable audio player

continous 4)
1. All voltage values are measured with respect to the ground pin.
2. Pd has been calculated with Tamb = 25°C, Tjunction = 150°C.
3. TS487 stands 1.5KV on all pins except standby pin which stands 1KV.
4. Attention must be paid to continous power dissipation (VDD x 300mA). Exposure of the IC to a short circuit for an extended time period is
dramatically reducing product life expectancy.
