TS3702
Micropower dual CMOS voltage comparators
Features
■ Push-pull CMOS output (no external pull-up
resistor required)
■ Extremely low supply current: 9μA typ /
comparator
■ Wide single supply range: 2.7V to 16V or dual
supplies (±1.35V to ±8V)
■ Extremely low input bias current: 1pA typ
■ Extremely low input offset currents: 1pA typ
■ Input common-mode voltage range includes
GND
■ High input impedance: 10¹²Î© typ
■ Fast response time: 2μs typ for 5mV overdrive
■ Pin-to-pin and functionally compatible with
bipolar LM393
Description
The TS3702 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9μA typ / comparator (20 times less than bipolar
LM393). The push-pull CMOS output stage allows
power and space saving by eliminating the
external pull-up resistor required by usual open-
collector output comparators.
Thus response times remain similar to the LM393.
