ADVANCE INFORMATION

Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-

eters are absolute voltages referenced to GND. The thermal resistance and power dissipation ratings are measured

under board mounted and still air conditions.

DC Electrical Characteristics

VBIAS (VS) = 15V, TA = 25°C unless otherwise specified. The VIN, and IIN parameters are referenced to GND and are

applicable to input leads: INA and INB. The VO and IO parameters are referenced to GND and are applicable to the

output leads: OUTA and OUTB.
