• Manufacturer Part Number: IP200
• Description: Interpolation Circuit for Incremental Measuring Systems
• Manufacturer: ETC [List of Unclassifed Manufacturers]

1
The IP200 interpolation circuit is designed for connection to incremental position and angle measuring
systems with sine-shaped output signals with a 90° phase shift. It can be operated at a large number of
transducer systems working according to the most varied measuring principles. With a maximum
interpolation rate of 200 the IC is capable to split the input signal period into up to 200 segments. A counter
value can be output via parallel or serial interface, respectively.
Different interfaces and flexible configuration types enable the use of the IP200 in single-chip interpolation
systems, in microcontroller-based measuring devices and in multi-channel systems alike. Proprietary
automatic gain and offset control, as well as the possibility of a analogue phase correction ensure a high
measuring precision under industrial conditions. The integrated two-level measuring value trigger and the
additional parallel high speed output makes the IC suitable for use in real time applications.
