INTRODUCTION
The SMD1108 is a versatile, programmable 8-channel, 10-bit Data Acquisition System that is designed to operate autonomously, relieving the system host and logic board of the environmental monitoring tasks.
Programming of configuration, control and calibration values by the user can be simplified with the interface adapter and Windows GUI software obtainable from Summit Microelectronics.
