Our high-speed comparators offer nanosecond propagation delay with the lowest power consumption on the market, available in space-saving SOT-23 and SC-70 packages.

High speed comparators offering micropower consumption

The TS3011 single comparator has stable and fast response time 8 ns typical. The current consumption is below 1 mA.

The TS3021 and TS3022  single and dual comparators feature high-speed response time with rail-to-rail inputs. Both comparators offer micropower consumption as low as a few tens of microamperes.
