LT1012A/LT1012
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range of 0
°C ≤ TA ≤ 70°C. VS = ±15V, VCM = 0V, unless otherwise noted.
Optional Offset Nulling and Overcompensation
Circuits
Input offset voltage can be adjusted over a
±800V range
with a 5k to 100k potentiometer.
The LT1012 is internally compensated for unity gain
stability. The overcompensation capacitor, CS, 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 VMIN ≤ VS ≤ ±20V and
–13.5V
≤ VCM ≤ 13.5V (for VS = ±15V). VMIN = ±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.
