(Prototype chips are available for demonstration. Final product version will be ready by Q1/2021.)
The RDC1001 device is a 16-bit resolution resolver/LVDT-to-digital converter, which is capable of reading the sine and cosine angle from a resolver sensor, or the linear distortion from a LVDT sensor (selectable by setting a switch). The converter accepts 1.2 Vpp input signals, in the range of 2.5 kHz to 20 kHz on the sine and cosine inputs. When it is used to read out a resolver, a digital type II servo loop is employed to track the inputs and convert the input sine and cosine information into a digital representation of the input angle and velocity. When it is connected to a LVDT, a ratiometric conversion is applied to calculate the linear distortion.
