INTRODUCTION
The ZN429 is an 8-bit D-A converter. It contains an
advanced design of R-2R ladder network and an array of
precision bipolar switches on a single monolithic chip.
The special design of the ladder network results in full
8-bit accuracy using normal diffused resistors.
The converter is of the voltage switching type and uses
an R-2R resistor ladder network as shown in Fig.3.
Each 2R element is connected either to 0V or V
transistor switches specially designed for low offset voltage
(typically 1mV).
REF
by
Binary weighted voltages are produced at the output of
the R-2R ladder, the value depending on the digital number
applied to the bit inputs.
An external fixed or varying reference is required which
should have a slope resistance less than 2
Suggested external reference sources are the ZN404 or
one of the ZN458 range. Each ZN404 is capable of supplying
up to five ZN429 circuits and this is increased to ten for the
ZN458 range.
