The MAX971–MAX974 and MAX981–MAX984 single/

dual/quad low-voltage comparators feature the lowest

p owe r c ons ump tion a va ila b le . The s e mic rop owe r

d e vic e s d ra w le s s tha n 4µA s up p ly c urre nt ove r

temperature (MAX971/MAX972, MAX981/MAX982), and

inc lud e a n inte rna l 1.182V ± 1% (MAX971/MAX973/

MAX974) or ±2% (MAX981–MAX984) voltage reference

and programmable hysteresis.

♦ µMAX Package—Smallest 8-Pin SO

(MAX9_1/MAX9_2/MAX9_3)

♦ Ultra-Low 4µA Max Quiescent Current

Over Extended Temp. Range (MAX971/MAX981)

♦ Power Supplies: Single +2.5V to +11V

Dual ±1.25V to ±5.5V

♦ Input Voltage Range Includes Negative Supply

♦ Internal 1.182V ±1% Bandgap Reference

Ideal for 3V or 5V single-supply applications, these

devices operate from a single +2.5V to +11V supply (or

±1.25V to ±5.5V dual supplies), and each comparator’s

input voltage ranges from the negative supply rail to within

1.3V of the positive supply.

♦ 12µs Propagation Delay (10mV Overdrive)

♦ Output Has Separate GND Pin (MAX9_1/MAX9_4)

The single MAX971 and MAX981 and the dual MAX973

and MAX982/MAX983 provide a unique, simple method

for adding hysteresis without feedback or complicated

e q ua tions , s imp ly b y us ing the HYST p in p lus two

resistors.

Oscillator Circuits

The MAX971–MAX974 and MAX981–MAX984’s open-

drain outputs permit wire-ORed configurations. Thanks to

an 11V output range and separate GND pin for the output

transistor (MAX971/MAX974, MAX981/MAX984), these

devices are ideal for level translators and bipolar to single-

ended converters. For similar devices with complementary

output stages, see the MAX921–MAX924 (1% reference)

and the MAX931–MAX934 (2% reference).
