The ZN425 is a monolithic 8-bit D-A converter containing an R-2R ladder network of diffused resistors with precision bipolar switches, and in addition a counter and a 2.5V precision voltage reference. The ZN425 counter is a powerful addition which allows a precision staircase to be generated very simply by clocking the counter.
