iC-NQL 13-Bit Sin/D-Converter
Applications
- Interpolator IC for position data acquisition from analog sine/cosine sensors
- Optical linear/rotary encoders
- MR sensor systems
Features
- Resolution of up to 8192 angle steps per sine/cosine period
- Binary and decimal resolution settings, e.g. 500, 512, 1000, 1024; programmable angle hysteresis
- Conversion time of just 250 ns including amplifier settling
- Count-safe vector follower principle, realtime system with 70 MHz sampling rate
- Direct sensor connection; selectable input gain
- Front-end signal conditioning (8 bit offset, 5 bit amplitude ratio, 6 bit phase)
- 250 kHz 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. 0.25 μs for 1 MHz 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
