The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifiers, i.e., out of 100 LT2179s (or 100
LT2178s) typically 240 op amps (or 120) will be better than the indicated
specification.
Note 2:
This parameter is tested on a sample basis only. All noise
parameters are tested with V
S
=
±
2.5V, V
O
= 0V.
Note 3:
This parameter is guaranteed by design and is not tested.
Note 4:
Power supply rejection ratio is measured at the minimum supply
voltage. The op amps actually work at 1.7V supply but with a typical offset
skew of –300
μ
V.
Note 5:
This parameter is not 100% tested.
Note 6:
During testing at –40
°
C, the 5V power supply turn-on time is less
than 0.5s.
Note 7:
The LT2178C/LT2179C are designed, characterized and expected
to meet the industrial temperature limits, but are not tested at –40
°
C and
85
°
C. I-grade parts are guaranteed.
