MICROCONTROLLER
Two modules have been added to this company's ADAIO family of precision analog I/O expansion solutions for embedded applications. These compact and versatile microcontroller-based devices provide both analog input and output, and employ the I²C Bus (Inter-Integrated Circuit). The TE1313 and TE1243 modules provide one digital-to-analog output channel with resolutions of 16 bits and 12 bits respectively, and one 16-bit bipolar/unipolar analog-to-digital input channel with an input range from 0.1 to ±10 V DC. They provide optically isolated data, with up to 1000 V of optical isolation, and onboard dc/dc converter to eliminate the need for a second isolated power. Their DAC Full Scale (FS) output range is selectable for 1.0 V FS, 5.0 V FS and 10.0 Vdc, while the units' microcontrollers provide median filtering for the ADC.
