SIGNAL PROCESSING
From sensor signal to precise position information.
AMAC interpolation ICs process sine/cosine sensor signals, correct signal deviations and generate high-resolution position information for integration into measurement and control systems.
1. Signal acquisition & conditioning:
Depending on the IC, sine, cosine and reference signals can be processed as differential or single-ended inputs across different signal ranges.
2. Signal correction & interpolation:
Available functions include gain and offset control, sensor- or scale-specific correction coefficients and device-dependent interpolation functions.
3. Outputs & system integration
Depending on the selected IC, interfaces include ABZ/LVTTL or TTL, SPI, SSI and BiSS, together with monitor outputs, error signals and configurable options.
Device-dependent features also include internal counters, EEPROM/pin-based configuration and different processing delays.
