iC-NQL
13-Bit Sin/D-Converter with Serial Synchronous Interface (SSI).
NOTE: NOT FOR NEW PROJECTS. PLEASE USE iC-NQC AS REPLACEMENT.
Features
Resolution of up to 8,192 angle steps per sine/cosine period.
Binary and decimal resolution settings, e.g. 500, 512, 1000, 1024; programmable angle hysteresis.
Conversion time of just 250ns including amplifier settling.
Count-safe vector follower principle, realtime system with 70MHz sampling.
Direct sensor connection; selectable input gain.
Front-end signal conditioning (8 bit offset, 5 bit amplitude ratio, 6 bit phase).
250kHz input frequency.
Absolute angle output via fast SSI interface.
24-bit on-chip multiturn counter.
A QUAD B incremental outputs with selectable minimum transition distance (e.g. 0.25µs for 1MHz at A).
Index signal processing adjustable in position and width.
Fault monitoring: frequency, amplitude, configuration (CRC).
Setup via serial EEPROM.
ESD protection and TTL-/CMOS-compatible outputs.
