16位正余弦插补细分器, 带自动校准

Features      

• Input frequency of up to 125 kHz

• Differential sine/cosine input signal range of 20 mV to 1.4 V peak-peak

• Binary/decimal interpolation factors from x0.25 to x16384

• Post-AB divider [1/1 to 1/32] allows fractional resolution

• Simple automatic one-pin calibration

• Easy configuration: by static pins (for generic ABZ output)

• Advanced configuration: 1-wire interface, 3 and 4-wire SPI (32 MHz), serial I2C EEPROM

• PWM or ABZ quadrature encoder output signals

• Incremental ABZ output to 8 MHz (32 MHz edge separation)

• Position and velocity read-out (32 bit SPI)

• Sophisticated error handling and signal monitoring

• Static 64 position LUT to compensate for arbitrary sensor distortions

• Supply voltage range of 3.1 V to 5.5 V

Applications

• Sine/cosine interpolation

• Signal conditioning with auto calibration

• Linear and rotary encoders

• Flexible incremental encoder systems
