ELECTRICAL CHARACTERISTICS
The ● denotes specifications which apply over the full operating temperature
range of –40°C ≤ T
A
≤ 125°C. V
S
= ±15V, V
CM
= 0V, V
OUT
= 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 θ
JA
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
85°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: V
S
= 5V limits are guaranteed by correlation to V
S
= 3V and
V
S
= ±15V tests.
Note 7: V
S
= 3V limits are guaranteed by correlation to V
S
= 5V and
V
S
= ±15V tests.
Note 8: Guaranteed by correlation to slew rate at V
S
= ±15V and GBW
at V
S
= 3V and V
S
= ±15V tests.
Note 9: This parameter is not 100% tested.
