The q denotes specifications which apply over the full operating
temperature range.
Note 1: Typical parameters are defined as 60% yield of parameter
distributions of individual amplifiers, i.e., out of 100 LT1465s (or 100
LT1464s) typically 240 op amps (or 120) will be better than the indicated
specification.
Note 2: The LT1464 and LT1465 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: in = (2qib)1/2 where
q = (1.6)(10)–19 coulomb. The noise of source resistors up to 1G
swamps the contribution of current noise.
Note 4: Slew rate is measured in AV = –1; input signal is ±7.5V, output is
measured at
±2.5V.
Note 5:
CMRR and PSRR are defined as follows:
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.
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 LT1465; between the two amplifiers on the
LT1464.
