DESCRIPTION
AA393
Low power dual voltage comparator
AA393 includes two independent precision voltage comparators. The maximum offset
voltage is as low as 2.0mV. Single power supply provides over a wide range of operating
voltages from 2V to 36V or Dual power supply from ±1V to ±18V. The IC is available
in
8-pin TSSOP
(AA393A) and
8-pin SOP
(AA393S) package.
