the individual characteristics of the two devices, the two
and three op amp instrumentation amplifier configura-
tions shown in this data sheet are examples. Matching
characteristics are not 100% tested on the LT2078/LT2079.
Some specifications are guaranteed by definition. For
example, 70
V maximum offset voltage implies that mis-
match cannot be more than 140
V. 95dB (= 17.5V/V)
CMRR means that worst-case CMRR match is 89dB
(= 35
V/V). However, Table 1 can be used to estimate the
expected matching performance at VS = 5V, 0V between
the two sides of the LT2078, and between amplifiers A and
D, and between amplifiers B and C of the LT2079.
Comparator Applications
The single supply operation of the LT2078/LT2079 and its
ability to swing close to ground while sinking current
lends itself to use as a precision comparator with TTL
compatible output.

THE USEFULNESS OF DIFFERENCE AMPLIFIERS IS LIMITED BY THE FACT THAT
THE INPUT RESISTANCE IS EQUAL TO THE SOURCE RESISTANCE. THE PICOAMPERE
OFFSET CURRENT AND LOW CURRENT NOISE OF THE LT2078 ALLOWS THE USE OF
1M SOURCE RESISTORS WITHOUT DEGRADATION IN PERFORMANCE. IN ADDITION,
WITH MEGOHM RESISTORS MICROPOWER OPERATION CAN BE MAINTAINED

THE LT2078 CONTRIBUTES LESS THAN 3% OF THE TOTAL OUTPUT NOISE AND

DEPENDS ON THE MATCHING OF THE TWO 1M RESISTORS
