temperature range.
Note 1: Typical parameters are defined as 60% yield of parameter
distributions of individual amplifiers, i.e., out of 100 LT1463s (or 100
LT1462s) typically 240 op amps (or 120) will be better than the indicated
specification.
Note 2: The LT1462 and LT1463 are designed, characterized and expected
to meet these extended temperature limits, but are not tested at – 40 C
and 85 C. Guaranteed I grade parts are available, consult factory.
Note 3: Current noise is calculated from the formula: i
q = (1.6)(10
the contribution of current noise.

Note 4: Slew rate is measured in A
measured at 2.5V.
Note 5: CMRR and PSRR are defined as follows:
Note 6: This parameter is not 100% tested.
Note 7: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1463; between the two amplifiers on the
LT1462.
CM
1. CMRR and PSRR are measured in V/V on the individual amplifiers.
2. The difference is calculated between the matching sides in V/V.
3. The result is converted to dB.
