DESCRIPTION

The NE/SE5018/19 is a complete 8-bit digital-to-analog converter

subsystem on one monolithic chip. The data inputs have input

latches which are controlled by a latch enable pin. The data and

latch enable inputs are ultra-low loading for easy interfacing with all

logic systems. The latches appear transparent when the LE input is

in the low state. When LE goes high, the input data present at the

moment of transition is latched and retained until LE again goes low.

This feature allows easy compatibility with most microprocessors.

The chip also comprises a stable voltage reference (5V nominal)

and high slew rate buffer amplifier. The voltage reference may be

externally trimmed with a potentiometer for easy adjustment of

full-scale while maintaining a low temperature coefficient.

The output of the buffer amplifier may be offset so as to provide

bipolar as well as unipolar operation.
