For operation of PrecVS-PGA-ADC 3.6, an additional "Switchable Bipolar Power Source" SBPS-LDO 3.12 (together with an included 9V plug-in power supply) and a package of 1-wire-bus stick, two 6p6c-RJ12 cables, USB memory stick with all librariers and the software) is required. The evaluation kit is operated through a 1-wire bus connector with a personal computer, an installed LabVIEW® runtime and the SensorControl software.
