b) When the input is more than 400mV below ground
(at 25°C), the input stage saturates (transistors Q3 and
Q4) and phase reversal occurs at the output. This can
cause lock-up in servo systems. Due to a unique phase
reversal protection circuitry (Q21, Q22, Q27, Q28), the
LT1013/LT1014’s outputs do not reverse, as illustrated
below, even when the inputs are at –1.5V.
Thereisonecircumstance,however,underwhichthephase
reversal protection circuitry does not function: when the
other op amp on the LT1013, or one specific amplifier of
the other three on the LT1014, is driven hard into negative
saturation at the output.
Phase reversal protection does not work on amplifier:
A when D’s output is in negative saturation. B’s and C’s
outputs have no effect.
B when C’s output is in negative saturation. A’s and D’s
outputs have no effect.
C when B’s output is in negative saturation. A’s and D’s
outputs have no effect.

D when A’s output is negative saturation. B’s and C’s
outputs have no effect.
At the output, the aforementioned single supply designs
either cannot swing to within 600mV of ground (OP-20)
orcannotsinkmorethanafewmicroampereswhileswing-
ing to ground (LM124, LM158). The LT1013/LT1014’s
all-NPNoutputstagemaintainsitslowoutputresistanceand
high gain characteristics until the output is saturated.
In dual supply operations, the output stage is crossover
distortion-free.
Comparator Applications
The single supply operation of the LT1013/LT1014 lends
itself to its use as a precision comparator with TTL com-
patible output:
In systems using both op amps and comparators, the
LT1013/LT1014 can perform multiple duties; for example,
on the LT1014, two of the devices can be used as op amps
and the other two as comparators.
