Programmable 9-Bit Sin/Cos Interpolation IC with RS422 Driver

iC-MQ is a real-time vector-tracking sine/cosine-to-digital converter with an angle resolution of up to 400.

The angle is output via fail-safe RS422 drivers as an encoder quadrature signal with index, glitch-free at a guaranteed minimum edge distance.

The signal-conditioning analog front-end takes differential or single-ended signals (current-to-voltage conversion is optional) and allows the correction of common signal errors.
All device functions are monitored, improper operation can be alarmed.
