摘要：A sensor arrangement for light sensing and temperature sensing comprises afirst sensor input () for connecting a temperature sensor () and a second sensor input ()for connecting a light sensor (), in particular an ambient light sensor. A sensor switch (S)electrically connects either the first or the second sensor input () to an integration input() of an integrating analog-to-digital converter (). A reference circuit () connects to theintegration input () via a first switch (S). A first reference input () of the integrating analog-to-digital converter () is to be connected with a first reference potential (Vb). A counter ()connects to an integration output () of the integrating analog-to-digital converter (). Anda controller unit () connects to the counter () and is designed to control the first switch(S) depending on an integrated sensor signal (Vout) integrated by the integrating analog-to-digital converter ().
