TS393

Micropower dual CMOS voltage comparators

Features

■ Extremely low supply current: typically 9 µA per

comparator

■ Wide single supply range 2.7 V to 16 V or dual

supplies (±1.35 V to ±8 V)

■ Extremely low input bias current: 1 pA typical

■ Extremely low input offset current: 1 pA typical

■ Input common-mode voltage range includes

ground

■ High input impedance: 10

Ω typ

■ Fast response time: 2.5 µs typ. for 5 mV

overdrive

■ Pin-to-pin and functionally compatible with dual

bipolar LM393

Description

The TS393 is a micropower CMOS dual voltage

comparator with extremely low consumption of

9 µA typically per comparator (20 times less than

the dual bipolar LM393). Similar performance is

offered by the dual micropower comparator

TS3702 with a push-pull CMOS output.

Thus response times remain similar to the LM393.
