ZN425J - FERRANTI

ZN425J 8-Bit D to A/A to D Converter

The ZN425E (or ZN425J) is a monolithic S.l.G. 8-bit digital to analogue convortor containing an R-2Rladder network of diffused resistors with precision bipolar rwltchos, and in addition a countor and a 2.5V precision voltag€ roference. The counter ir I powerful addition which allows a precision staircase to be generated y6ry rimply merely by clocking tho co.
