ACTIVE LOW (TS486) or

OUTPUT POWER: 102mW @5V, 38mW

LOW CURRENT CONSUMPTION:

2.5mA max

High Signal-to-Noise ratio: 103dB(A) at 5V

High Crosstalk immunity: 83dB (F=1kHz)

PSRR: 58 dB (F=1kHz), inputs grounded

SHORT CIRCUIT LIMITATION

Available in SO8, MiniSO8 & QFN 3x3mm

DESCRIPTION

The TS486/7 is a dual audio power amplifier capa-

ble of driving, in single-ended mode, either a 16 or

a 32鈩?stereo headset.

Capable of descending to low voltages, it delivers

up to 90mW per channel (into 16鈩?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

Headphone Amplifier

Mobile phone, PDA, computer motherboard

High end TV, portable audio player
