Comparators feature very low supply current

The LMV331and LMV393 single and dual comparators run from 2.7 to 5.5 V supplies and feature a low 40 μA/comparator (typ) supply current. They work over -40° to +125°C and their input common mode voltage range includes ground.

The dual version comes in MSOP-8, SO-8 packages and the LMV331 is available in small 5-Pin SOT353 or SOT25 packages. Offset voltage is 1.7 mv typical and 7 mv maximum with a drift of 5 μV/°C. Input bias current is 10 nA typ. and 400 na maximum over the full temperature range. From $0.11 ea/1,000.
