Comparator Applications

Sometimes it is desirable to use an op amp as a compara-

tor. When operating the LT1215/LT1216 on a single 3.3V

or 5V supply, the output interfaces directly with most TTL

and CMOS logic.

The response time of the LT1215/LT1216 is a strong

function of the amount of input overdrive as shown in the

following photos. These amplifiers are unity-gain stable

op amps and not fast comparators, therefore, the logic

being driven may oscillate due to the long transition time.

The output can be speeded up by adding 20mV or more of

hysteresis (positive feedback), but the offset is then a

function of the input direction.
