Optional Offset Nulling and Overcompensation Circuits
5k TO 100k POT 1 Input offset voltage can be adjusted over a ± 800µV range 2 – 8 7 with a 5k to 100k potentiometer. 6 LT1012 OUT 3 5 The LT1012 is internally compensated for unity gain + 4 stability. The overcompensation capacitor, C C S, can be S used to improve capacitive load handling capability, to V– narrow noise bandwidth, or to stabilize circuits with gain LT1012A • EC01 in the feedback loop. sn1012 1012afbs 7
