TS339
Micropower Quad CMOS Voltage Comparators
■ Extremely low supply current: 9µa typ/comp.
■ 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 current: 1pA typ.
■ Input common-mode voltage range includes
GND
■ High input impedance: 10
12
Ω typ
■ Fast response time: 1.5µs typ. for 5mV
overdrive
■ Pin-to-pin and functionally compatible with
bipolar LM339
Description
The TS339 is a micropower CMOS quad voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM339). Similar performances are offered by the
quad micropower comparator TS3704 with a
push-pull CMOS output.
Thus response times remain similar to the LM339.
