MICROPOWER DUAL CMOS VOLTAGE COMPARATORS

TS393C,I,M

■ EXTREMELY LOW SUPPL Y CURRENT :

9µA typ / comparator

■ WIDE SINGLE SUPPLY RANGE

2.7V TO 16V OR DUAL SUPPLIES

(±1.35V TO ±8V)

■ EXTREMELY LOW INPUT BIAS CURRENT :

1pA typ

■ EXTREMELY L OW IN PUT OF F SET

CURRENTS : 1pA typ

■ INPUT COMMON-MODE VOLTAGE RANGE

INCLUDES GND

■ HIGH INPUT IMPEDANCE : 10

12

Ω typ

■ FAST RESPO NSE TIME : 2.5µs typ for

5mV overdrive

■ PIN-TO-PIN AND FUNCTIONALLY

COMPATIBLE WITH BIPOLAR LM393

DESCRIPTION

The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM393). Similar performances are offered by the dual micropower comparator TS3702 with a push-pull CMO S outpu t.

Thus response times remain similar to the LM393.

1. All volta ge values, except differential voltage, are w i th respect to network grou nd t erminal.

2. Differe nt i al voltages are the non-i nverting i nput termi nal with respect to the inverting input terminal .

3. Excursion s of input voltages may exceed the power supply leve l . As long as the common m ode voltage [V within the specified range, the comparator will pr ovide a stable ou tput state. H owever, the maximum cur rent throu gh the ESD diode s (if) of the input stage must st ri ct l y be observ ed. The output m ust never ex ceed the pow er supply voltage.
