7 / 20 page 7 sn1012 1012afbs 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 ±800µV 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.
