APPLICATION INFORMATION
comparator applications
The single-supply operation of the LT1013 lends itself for use as a precision comparator with TTL-compatible
output. In systems using both operational amplifiers and comparators, the LT1013 can perform multiple duties.
Refer to Figures 25 and 26.

low-supply operation
The minimum supply voltage for proper operation of the LT1013 is 3.4 V (three Ni-Cad batteries). Typical supply
current at this voltage is 290
μ
A; therefore, power dissipation is only 1 mW per amplifier.
offset voltage and noise testing
The test circuit for measuring input offset voltage and its temperature coefficient is shown in Figure 30. This
circuit with supply voltages increased to
±
20 V is also used as the burn-in configuration.
The peak-to-peak equivalent input noise voltage of the LT1013 is measured using the test circuit shown in
Figure 27. The frequency response of the noise tester indicates that the 0.1-Hz corner is defined by only one
zero. The test time to measure 0.1-Hz to 10-Hz noise should not exceed 10 seconds, as this time limit acts as
an additional zero to eliminate noise contribution from the frequency band below 0.1 Hz.
An input noise voltage test is recommended when measuring the noise of a large number of units. A 10-Hz input
noise voltage measurement correlates well with a 0.1-Hz peak-to-peak noise reading because both results are
determined by the white noise and the location of the 1/f corner frequency.
Current noise is measured by the circuit and formula shown in Figure 28. The noise of the source resistors is
subtracted.
