Description
The TS3704 is a micropower CMOS quad voltage comparator with extremely low consumption of 9μA typ / comparator (20 times less than bipolar LM339). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual opencollector output comparators.
FEATUREs
■ Push-pull CMOS output (no external pull-up resistor required)
■ Extremely low supply current: 9μa typ per 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 current: 1pA typ
■ Input common-mode voltage range includes GND
■ High input impedance: 1012Ω typ
■ Last response time: 2μs typ. for 5mV overdrive
■ Pin-to-pin and functionally compatible with bipolar LM339
