... For example, the 75µV maximum offset voltage in these low cost packages is the lowest on any dual or quad non-chopper op amp. The LT1112/LT1114 also provide a full set of matching specifications, facilitating their use in such matching dependent applications as two and three op amp instru- mentation amplifiers. ...

... Note 3: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers; i.e., out of 100 LT1114s (or 100 LT1112s) typically 240 op amps (or 120) will be better than the indicated specification. Note 4: This parameter is guaranteed by design and is not tested. LT1112/LT1114 = ±15V, unless otherwise noted. ...

... The well-known triple op amp configuration illustrates these concepts. Output offset is a function of the difference between the offsets of the two halves of the LT1112. This error cancellation principle holds for a considerable num- ber of input referred parameters in addition to offset voltage and its drift with temperature. Input bias current ...

... impedance sources, the LT1114 is recommended because its CMRR vs frequency performance is better than the LT1112’s. For example, with two matched 1MΩ source GAIN = 1000 TRIM R8 FOR GAIN resistors, CMRR at 100Hz is 100dB with the LT1114, 76dB TRIM R9 FOR DC with the LT1112. ...
