MAG-POS

Rad-Hard Resolver/LVDT Interface IC

The MAG-POS00002-NP is a radiation-tolerant resolver- and LVDT-to-digital converter. The MAGPOS00002-NP is designed to readout the angular information from a resolver or the linear displacement information from an LVDT. The MAG-POS00002-NP is capable of reading the position of a resolver or LVDT in a 16-bit resolution at the speed of up to 40k samples/s.
