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.


Description

of driving, in single-ended mode, either a 16 or a 32W stereo headset.

TS487 Capable of descending to low voltages, it delivers up to 90mW per channel (into 16W loads) of continuous 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 version.
