Comparators with 2% Reference
____________________________Features
♦ Ultra-Low 4µA Max Quiescent Current
Over Extended Temp. Range (MAX931) Ideal for 3V or 5V single-supply applications, the
MAX931-MAX934 operate from a single +2.5V to +11V
supply (or a ±1.25V to ±5V dual supply), and each
comparator’s input voltage range extends from the
negative supply rail to within 1.3V of the positive supply. ♦ Internal 1.182V ±2% Bandgap Reference The MAX931-MAX934’s unique output stage continuously
sources as much as 40mA. And by eliminating powersupply glitches that commonly occur when comparators
change logic states, the MAX931-MAX934 minimize
parasitic feedback, which makes them easier to use. ♦ No Switching Crowbar Current ♦ Power Supplies:
Single +2.5V to +11V
Dual ±1.25V to ±5.5V
♦ Input Voltage Range Includes Negative Supply
♦ Adjustable Hysteresis
♦ TTL-/CMOS-Compatible Outputs
♦ 12µs Propagation Delay (10mV Overdrive)
♦ 40mA Continuous Source Current
♦ Available in Space-Saving µMAX Package The single MAX931 and dual MAX932/MAX933 provide a
unique and simple method for adding hysteresis without
feedback and complicated equations, using the HYST pin
and two resistors. ______________Ordering Information …
