Micropower ADC and DAC in SO-8 give PCs a 12-bit analog interface
Kevin R. Hoskins
Abstract
The use of the LTC1298 analog-to-digital converter and the LTC1446 digital-to-analog converter in SO-8 to give PCs a 12-bit analog interface is described.

Introduction
Adding two channels of analog input/output to a PC computer is simple, inexpensive, low powered and compact when using the LTC1298 ADC and LTC1446 DAC. The LTC1298 and the LTC1446 are the first SO-8 packaged 2-channel devices of their kind. While the application shown is for PC data acquisition, the two converters provide the smallest, lowest power solutions for many other analog I/O applications.
