MAX44268

1.3mm x 1.3mm, Low-Power

Dual Comparator with Reference

Typical Operating Characteristics

(VCC = 5V, VGND = 0V, VIN- = VIN+ = 1.236V, RPULLUP = 100kΩ to VCC, TA = -40NC to +85NC. Typical values are at TA = +25NC, unless

otherwise noted. All devices are 100% production tested at TA = +25NC. Temperature limits are guaranteed by design.)
