TS3702

Micropower dual CMOS voltage comparators

Features

■ Push-pull CMOS output (no external pull-up

resistor required)

■ Extremely low supply 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 low input offset currents: 1pA typ

■ Input common-mode voltage range includes

GND

■ High input impedance: 10

Ω typ

■ Fast response time: 2μs typ for 5mV overdrive

■ Pin-to-pin and functionally compatible with

bipolar LM393

Description

The TS3702 is a micropower CMOS dual voltage

comparator with extremely low consumption of

9μA typ / comparator (20 times less than bipolar

LM393). 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 LM393.
