8-Bit µp-compatible D/A converter
Product specification
NE/SE5018/5019
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.
