Note 4:
Slew rate is measured in AV = –1; input signal is ±7.5V, output is temperature range. measured at ±2.5V.
Note 1:
Typical parameters are defined as 60% yield of parameter
Note 5:
∆CMRR and ∆PSRR are defined as follows: distributions of individual amplifiers, i.e., out of 100 LT1465s (or 100 1. CMRR and PSRR are measured in µV/V on the individual amplifiers. LT1464s) typically 240 op amps (or 120) will be better than the indicated 2. The difference is calculated between the matching sides in µV/V. specification. 3. The result is converted to dB.
Note 2:
The LT1464 and LT1465 are designed, characterized and expected

This parameter is not 100% tested. to meet these extended temperature limits, but are not tested at – 40°C
Note 7:
Matching parameters are the difference between amplifiers A and and 85°C. Guaranteed I grade parts are available, consult factory. D and between B and C on the LT1465; between the two amplifiers on the
Note 3:
Current noise is calculated from the formula: in = (2qib)1/2 where LT1464. q = (1.6)(10)–19 coulomb. The noise of source resistors up to 1GΩ swamps the contribution of current noise. 4
