The TS391 is a low-power, single voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The TS391 has a wide single supply voltage range or dual supplies of 2V to 36V or ±1V to ±18V. It has very low supply current (0.2 mA) independent of supply voltage (1 mW / comparator at 5 V) and low input bias current: 25 nA typ. It also has low input offset current: ± 5 nA typ. and low input offset voltage: ± 2 mV max. for TS391A
