On-chip filters

TTL output.

+5v Power supply

Low power consumption

40-Pin DIP

Description

The DAQ93P03 is a 6 channel digital sensor

preconditioning

circuit

interface

external

mechanical

switches

inductive/conductive

proximity switches to TTL circuits. The chip itself

consist of internal Schmitt Triggers to shape the

external On-Off level input, moreover, RC filter

function is also integrated inside the chip to eliminate

sharp noises carried by the external sensors. No

external filter should be used for DAQ83Q03 since it

has integrated digital filter itself, but external filter

circuit has to be used for 8253/8254 counters. The

filter function can be achieved by connect filter pins

to the ground of DAQ93P03.
