iC-WT Overview
The device iC-WT is an evaluator IC for optical increment linear and rotary motion sensors, e.g. glass scales or shaft encoders. A photodiodes array supplies the input signals for the monolithically integrated amplifiers, parators and the TTL patible push-pull output drivers.
iC-WT Key Features
- Differential scanning for track A and B
- Photocurrent amplifier with high cut-off frequency
- Current parators with hysteresis
- Index track Z selectable gated by tracks A and B
- Current-limited and short-circuit-proof push-pull outputs
- Outputs TTL patible
- Adjustable LED current control for constant optical receiver
- Integrated 50mA driver for the transmit LED
- LED current monitoring and error message upon violating
- Low current consumption from single 5V power supply ◊ Option: enhanced temperature range -40..125°C
