ELECTRICAL CHARACTERISTICS

The q denotes specifications which apply over the specified temperature range, otherwise specifications are TA = 25°C.

VS = ±5V, VCM = 0V,VOUT = 0V, for the 6-lead part VSHDN = V–, unless otherwise specified.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: A heat sink may be required to keep the junction temperature

below absolute maximum.

Note 3: VS = 5V limits are guaranteed by correlation to VS = 3V and

VS = ±5V or VS = ±9V tests.

Note 4: VS = 3V limits are guaranteed by correlation to VS = 5V and

VS = ±5V or VS = ±9V tests.

Note 5: Guaranteed by correlation to slew rate at VS = ±5V, and GBW at

VS = 3V and VS = ±5V tests.

Note 6: This specification implies a typical input offset voltage of 1.8mV at

VCM = 18V and a maximum input offset voltage of 7.2mV at VCM = 18V.

Note 7: This parameter is not 100% tested.

Note 8: Specifications apply to 6-lead SOT-23 with shutdown.

Note 9: Full-power bandwidth is calculated from the slew rate.

FPBW = SR/2

πVP.

Note 10: The LT1783 is guaranteed functional over the operating

temperature range – 40

°C to 85°C.
