... 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. ...

... Note 5: Offset voltage, supply current and power supply rejection ratio are measured at the minimum supply voltage. Note 6: Matching parameters are the difference between amplifiers A and D and between B and C on the LT1114; between the two amplifiers on the LT1112. Note 7: This parameter is the difference between two noninverting input bias currents. Note 8: ∆ ...

... The LT1112 in the S8 surface mount package has the standard pin configuration, i.e., the same configuration as the plastic and ceramic DIP packages. The LT1114 quad is offered in the narrow 16-pin surface mount package. All competitors are in the wide 16-pin package which occupies 1.8 times the area of the narrow package ...

... 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. COMMON MODE REJECTION TRIM R10 FOR AC ...
