The iC-Gi22 dual-channel inductive sensor IC with sin/cos and interpolated SSI data output is used for magnetic off-axis position sensing using a simple metal target. The device enables absolute angle detection over the entire mechanical revolution by sampling two separate channels (master plus slave). The demodulated receiver signals feed the external processor, i.e. a suitable nterpolation device such as the iC-MNF, iC-TW29, iC-NQE, and an MCU with ADCs, to determine the position with higher resolution.

Features:

• Adjustable transmitter with coil driver (2-5 MHz, up to 20 mA)
• Two independent receiver channels with demodulation and line driver (1 Vdiff @ 100 Ω)
• High level output with selectable center voltage
• Adjustable coarse (x1...10) and fine gain (x1...20)
• Precision offset correction (via 11 bits up to 200 mV)
• Automatic gain control (per channel)
• Sin/cos interpolation with 8-bit resolution (1 channel)
• Angle output via SSI with error and warning
• I2C multi-master for self-configuration from external EEPROM
• I2C slave interface to the system (MCU)
• Operation monitoring with alarm masking: signal loss, I/O short circuit, RAM CRC
• Signal frequency up to 50 kHz (allows for 90000 rpm minimum)
• Power supply from 3.3 V to 5 V, approx. 15 mA
• Space-saving 32-pin QFN with 5x5 mm
