For the fast and safe position acquisition with sine/cosine encoders and linear systems iC-MR provides the complete position sensor and encoder interface in a “system-on-chip” solution. The intrinsically safe differential sine/cosine transmission of the position information can take place now at signal frequencies of up to 500 kHz from the transmitter to the receiver.
The circuitry contains serial and parallel MCU interfaces and the complete analog front end for signal conditioning, a 13-bit sample & hold SAR tangent converter with a latency of only 2 µs, diagnostic functions for monitoring the sine/cosine signals in real time, as well as a 1V output driver for a differential sin/cos output at 100 Ω.
