Programmable integrated circuit GC-IP1000

converteranalog3 channel

The interpolation circuit GC-IP1000B is intended for connection to incremental position and angle measuring systems with sinusoidal output signals phase-shifted by 90 °. The extremely high resolution is achieved with an interpolation rate of up to 1000 times. The counter value is provided via the serial interface. At the same time, the output data can be output as square-wave pulses for external process processing. The GC-IP1000B can be operated on a large number of encoder systems that work according to the most varied of measuring principles. Various interfaces and flexible configuration types enable use in single-chip interpolation systems, in µC-based measuring devices as well as in multi-channel systems. A patented gain and offset control as well as a programmable phase correction guarantee a high measurement accuracy under industrial conditions. Thanks to the integrated measured value trigger, the GC-IP1000B is suitable for use in real-time applications. • Analog input 3 channels differential: sine/cosine/reference signal Standard connection 1Vpp (differential) Input ranges: 100mVpp, 120mVpp, 145mVpp (differential)Single-ended input 2.0Vpp Input frequency of up to 110kHz • AD-converter : internal converter max. 340kS/s • Signal correction : Automatic offset and amplitude controller Digital potentiometer for phase • Interpolation rate : 1000 / 800 / 500 / 400 / 250 / 200 / 125 /100 Output for measuring values 28-bit counting value 90° square-wave sequences or up/down counting pulses Error signal • Configuration options : Via configuration pins Via serial interface (SPI) Via EEPROM
