The
G
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: i
n
= (2qi
b
)
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 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.
