General Description
The E931.08 integrated circuit is designed for interfacing Thermopile sensors with microcontrollers or processors. A single wire Data Out, Clock In (DOCI™) interface is provided for interfacing with a micro-controller. Multiple devices can easily be operated at the same time.
One thermopile sensor connects directly to the analog inputs of the IC. The sensor signal is converted to a 17 bit digital value. The E931.08 contains an on chip temperature measurement circuit with a resolution of better than 0.02K.
A 14 bit temperature value as well as a 17 bit sensor value is supplied to an external microcontroller through the DOCI™ interface.
