Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
The inputs are protected by back-to-back diodes. Current limiting
resistors are not used in order to achieve low noise. If differential input
voltage exceeds
±
1.4V, the input current should be limited to 25mA. If the
common mode range exceeds either rail, the input current should be
limited to 10mA.
Note 3:
A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4:
The LT1678C/LT1679C and LT1678I/LT1679I are guaranteed
functional over the Operating Temperature Range of –40
°
C to 85
°
C.
Note 5:
The LT1678C/LT1679C are guaranteed to meet specified
performance from 0
°
C to 70
°
C. The LT1678C/LT1679C are designed,
characterized and expected to meet specified performance from –40
°
C to
85
°
C but is not tested or QA sampled at these temperatures. The LT1678I/
LT1679I are guaranteed to meet specified performance from –40
°
C to
85
°
C.
Note 6:
Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifier; i.e., out of 100 LT1678/LT1679s,
typically 60 op amps will be better than the indicated specification.
Note 7:
See the test circuit and frequency response curve for 0.1Hz to10Hz
tester in the Applications Information section.
Note 8:
Noise is 100% tested at
±
15V supplies.
Note 9:
Slew rate is measured in A
V
= –1; input signal is
±
10V, output
measured at
±
5V.
Note 10:
This parameter is not 100% tested.
Note 11:
V
S
= 5V limits are guaranteed by correlation to V
S
= 3V and
V
S
=
±
15V tests.
Note 12:
V
S
= 3V limits are guaranteed by correlation to V
S
= 5V and
V
S
=
±
15V tests.
Note 13:
Guaranteed by correlation to slew rate at V
S
=
±
15V and GBW at
V
S
= 3V and V
S
=
±
15V tests.
Note 14:
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 15:
Matching parameters are the difference between amplifiers A and
B on the LT1678 and between amplifiers A and D and B and C in the
LT1679.
Note 16:
Input range guaranteed by the common mode rejection ratio test.
