ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating temperature

range of – 40

°C ≤ TA ≤ 125°C. VS = ±15V, VCM = 0V, VOUT = 0V unless otherwise noted. (Note 4)

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

of the device may be impaired.

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

below absolute maximum. This depends on the power supply voltage and

how many amplifiers are shorted. The

θJA specified for the DD and DHC

package is with minimal PCB heat spreading metal. Using expanded metal

area on all layers of a board reduces this value.

Note 3: The LT1490AC/LT1491AC and LT1490AI/LT1491AI are guaranteed

functional over the operating temperature range of – 40

°C to 85°C. The

LT1490AH/LT1491AH are guaranteed functional over the operating

temperature range of – 40

°C to 125°C.

Note 4: The LT1490AC/LT1491AC are guaranteed to meet specified

performance from 0

°C to 70°C. The LT1490AC/LT1491AC are designed,

characterized and expected to meet specified performance from – 40

°C to

°C but are not tested or QA sampled at these temperatures. The

LT1490AI/LT1491AI are guaranteed to meet specified performance from

–40

°C to 85°C. The LT1490AH/LT1491AH are guaranteed to meet

specified performance from – 40

°C to 125°C.

Note 5: ESD (Electrostatic Discharge) sensitive device. Extensive use of

ESD protection devices are used internal to the LT1490A/LT1491A.

However, high electrostatic discharge can damage or degrade the device.

Use proper ESD handling precautions.

Note 6: VS = 5V limits are guaranteed by correlation to VS = 3V and

VS = ±15V tests.

Note 7: VS = 3V limits are guaranteed by correlation to VS = 5V and

VS = ±15V tests.

Note 8: Guaranteed by correlation to slew rate at VS = ±15V and GBW

at VS = 3V and VS = ±15V tests.

Note 9: This parameter is not 100% tested.
