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 open-collector output comparators.
Thus response times remain similar to the LM339.
主要特性
- High input impedance: 1012Ωtyp
- Input common-mode voltage range includes GND
- Pin-to-pin and functionally compatible with bipolar LM339
- Push-pull cmos output (no external pull-up resistor required)
- Wide single supply range 2.7V to 16V or dual supplies (±1.35V to ±8V)
- Extremely low supply current: 9µa typ/comp.
- Extremely low input offset current: 1pA typ.
- Last response time: 2µs typ. for 5mV overdrive
- Extremely low input bias current: 1pA typ.
