ELECTRICAL CHARACTERISTICS
The ● denotes the specifications which apply over the full operating
temperature range of 0°C ≤ T
A
≤ 70°C. V
S
= ± 15V, V
CM
= 0V, unless otherwise noted.
Optional Offset Nulling and Overcompensation
Circuits
Input offset voltage can be adjusted over a ± 800µV range
with a 5k to 100k potentiometer.
The LT1012 is internally compensated for unity gain
stability. The overcompensation capacitor, C
S
, can be
used to improve capacitive load handling capability, to
narrow noise bandwidth, or to stabilize circuits with gain
in the feedback loop.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential input voltages greater than 1V will cause excessive
current to flow through the input protection diodes unless limiting
resistance is used.
Note 3: These specifications apply for V
MIN
≤ V
S
≤ ± 20V and
–13.5V
≤ V
CM
≤ 13.5V (for V
S
= ± 15V). V
MIN
= ±1.2V at 25°C, ± 1.3V from
0°C to 70°C, ± 1.5V from – 55°C to 125°C.
Note 4: 10Hz noise voltage density is sample tested on every lot. Devices
100% tested at 10Hz are available on request.
Note 5: This parameter is tested on a sample basis only.
