Dual version of TLV3691 comparator?

Other Parts Discussed in Thread: TLV3691, TLV3702, TLV3492, LPV802, TLV8802, SN74LV1T34

Hello,

I'm looking for exactly what's in the subject line -- a dual version of the TLV3691 comparator. Based on the parametric search, it doesn't look like there is such a part but maybe I overlooked something? I need it to run at very low power from a 4.5v supply and need push-pull output.

Anyone, anything?

Thanks!

Brian,

Here are 16 dual push/pull comparators sorted by IQ.

Hi Brian,

There isn't a dual of the TLV3691, but there are other dual, very low power comparators having push-pull outputs. Take a look at the TLV3492 and TLV3702:

Let us know if you have any questions.

Sorry that the dual version of the TLV3691 does not exist. I am not sure what your propagation delay needs are but one option would be for you to use our LPV802 or TLV8802 dual channel amplifier as your dual comparator. Power consumption is 325nA per channel. so it is higher than the tlv3691 but this is the lowest option we have to offer today.

Hello All,

What I actually needed was a logic level shifter from 3.3v to 4.5v. I had a TLV3691 on the board already and I was thinking of using a dual version with the second comparator doing the level shift. Instead, I just found the Little Logic SN74LV1T34 logic level shifter and I'm using that.

Thanks!
