TheZN425E(orZN425J)is an 8-bit dualmodedigitalto analogue/analogutoedigitalconverterl.t

The use of the on-chip referencevoltageis pin optionalto retainflexibility.An externalfixed or

By includingon the chip an 8-bit binarycountera, nalogueto digitalconversioncan be obtained
simplyby addingan externacl omparato(rZN424P)andclockinhibitgating(2N7400E).
By simply clockingthe counterthe ZN425Ecan be used as a self-containedprecisionramp
generator.
A logic input selectswitch is incorporatedwhich determineswhelherthe precisionswitchesaccept
, ithe outputsfrom the binarycounteror externaldigitalinputsdependingupon whelherthe control
signalis respectivelyhigh or low.
The converteris of the voltageswitchingtype and usesan R-2Rresistorladdernetworkas shown
