LT1016

UltraFast Precision

10ns Comparator

FEATURES

DESCRIPTIO

The LT^®1016 is an UltraFast 10ns comparator that inter-

facesdirectlytoTTL/CMOSlogicwhileoperatingoffeither

±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.

UltraFast^TM(10ns typ)

■

Operates Off Single 5V Supply or ±5V

■

Complementary Output to TTL

■

Low Offset Voltage

No Minimum Input Slew Rate Requirement

No Power Supply Current Spiking

Output Latch Capability

■

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,

input signal is slow moving or is low level.

APPLICATIO S

■

High Speed A/D Converters

High Speed Sampling Circuits

Line Receivers

Extended Range V-to-F Converters

Fast Pulse Height/Width Discriminators

Zero-Crossing Detectors

Current Sense for Switching Regulators

High Speed Triggers

■

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.

■

Crystal Oscillators

Linear Technology offers a wide range of comparators in

addition to the LT1016 that address different applications.
