APPLICATION INFORMATION
comparator applications
The single-supply operation of the LT1014 can be used as a precision comparator with TTL-compatible output.
In systems using both operational amplifiers and comparators, the LT1014 can perform multiple duties (see
Figures 25 and 26).

low-supply operation
The minimum supply voltage for proper operation of the LT1014 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
Figure 30 shows the test circuit for measuring input offset voltage and its temperature coefficient. 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 LT1014 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.
Noise current is measured by the circuit and formula shown in Figure 28. The noise of the source resistors is
subtracted.
