TYPICAL APPLICATIONS
LT1034BC-1.2
THE LT1078 CONTRIBUTES LESS THAN 3% OF THE TOTAL OUTPUT NOISE AND
DRIFT WITH TIME AND TEMPERATURE. THE ACCURACY OF THE –5V OUTPUT
DEPENDS ON THE MATCHING OF THE TWO 1M RESISTORS

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 LT1078 ALLOWS THE USE OF 1M SOURCE
RESISTORS WITHOUT DEGRADATION IN PERFORMANCE. IN ADDITION,
WITH MEGOHM RESISTORS MICROPOWER OPERATION CAN BE MAINTAINED
