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.

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
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
n
= (2qi
b
)
1/2
where
q = (1.6)(10)
–19
coulomb. The noise of source resistors up to 1G
Ω
swamps the contribution of current noise.
Note 4: Slew rate is measured in A
V
= –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
µ
V/V on the individual amplifiers.
2. The difference is calculated between the matching sides in
µ
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.
D and between B and C on the LT1465; between the two amplifiers on the
