iC-MSC
Sin/Cos Sensor Signal Conditioner with Fail-Safe 1 Vpp Line Driver
- PGA inputs for differential or single-ended signals up to 500 kHz
- Unity gain capable for high output sensors
- Selectable adaptation to voltage or current signals
Description
iC-MSC is a sine/cosine sensor signal conditioner with fail-safe 1 Vpp line driver outputs. The analog PGA front-end takes differential or single-ended signals; current-to-voltage conversion is optional. For ultra-low latency, the signal-path is purely analog from input to output, whereas signal errors are corrected by a digitally-controlled conditioning unit utilizing several D/A converters. Signal loss detection and level monitoring is included.
