TS372 Low power dual CMOS voltage comparator Features ■ Wide single supply range or dual supplies 3 V to 16 V or ±1.5 V to ±8 V ■ Very low supply current: 0.1 mA/comparator independent of supply voltage ■ Extremely low input bias current: 1 pA typ ■ Extremely low input offset currents: 1 pA typ ■ Low input offset voltage ■ Input common-mode voltage range includes GND ■ Low output saturation voltage 150 mV typical ■ Output compatible with TTL, MOS and CMOS ■ High input impedance: 1012 Ω typical ■ Fast response time: 200 ns typ for TTL level input step N DIP8 (plastic package) D SO8 (plastic micropackage) Applications ■ Battery powered electronics ■ General-purpose portable device ■ General-purpose low voltage application Pin connections (top view) Description  These devices consist of two independent precision voltage comparators, designed to operate with single or dual supplies.   These differential comparators use the STMicroelectronics silicon lin MOS process giving them an excellent consumption-speed ratio.  These devices are ideally suited for low consumption applications.      /UTPUT  )NVERTING)NPUT  .ON INVERTING)NPUT  6 ##  .ON INVERTING)NPUT  )NVERTING)NPUT  /UTPUT  6## April 2011 Doc ID 4068 Rev 2 1/10 www.st.com 10 Application schematic TS372 1 Application schematic Figure 1.

Maximum power supply voltage when the comparator is not switching. 2. All voltage values, except differential voltage, are with respect to network ground terminal. 3. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 4. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage. 5. Guaranteed by design. 6. Short-circuit from outputs to Vcc+ can cause excessive heating and eventual destruction. 7.
