AME811/AME811A/AME811R
3-1/2 Digit A/D Converter - Low Power
With HOLD And Differential Reference Inputs
Notes: 1.Input voltage may exceed the supply voltages provided the input current is limited to
±
100
μ
A.
2.Dissipation rating assumes a device is mounted with all leads soldered to printed circuit board.
