Rare ic signetics N5018 NE5018N 8-bit d/a converter
8-Bit mp-compatible D/A converter
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.
This Chip NE5018 is very rare and hard to find - Nice collectable piece of vintage computer history. Date code 8335
