The TIDA-00202 reference design implements an EMC compliant industrial hybrid analog and digital interface to a HIPERFACE position encoder. A 3.3V supply RS485 transceiver with IEC-ESD and IEC-EFT protection is used for the bidirectional parameter channel. For the analog sin/cos signal channel: two options are provided to offer flexibility for connection to processors with and without embedded ADC or redundancy by using both options simultaneously. The first option features a fully differential dual 12-bit ADC with SPI output: the second option features a dual differential input with single-ended analog output (0-3.3V). The design features an industrial compliant 24V input with wide range from 16V to 36V. The power supply for the encoder can be configured from 7 to 12V (default 11V) and offers short-circuit protection. A 3.3V I/O connector with analog and logic signals provides an easy interface to a host processor with HIPERFACE master IP core. For quick evaluation an example firmware is available for a C2000™ Piccolo MCU to calculate the absolute angle position and display it through virtual COM port.
