DESCRIPTIO
The LT
faces directly to TTL/CMOS logic while operating off either
±5V or single 5V supplies. Tight offset voltage specifica-
tions and high gain allow the LT1016 to be used in
precision applications. Matched complementary outputs
further extend the versatility of this comparator.
A unique output stage provides active drive in both direc-
tions for maximum speed into TTL/CMOS logic or passive
loads, yet does not exhibit the large current spikes found
in conventional output stages. This allows the LT1016 to
remain stable with the outputs in the active region which,
greatly reduces the problem of output “glitching” when the
input signal is slow moving or is low level.
The LT1016 has a LATCH pin which will retain input data
at the outputs, when held high. Quiescent negative power
supply current is only 3mA. This allows the negative
supply pin to be driven from virtually any supply voltage
with a simple resistive divider. Device performance is not
affected by variations in negative supply voltage.
Linear Technology offers a wide range of comparators in
addition to the LT1016 that address different applications.
