IC-MA Datasheet, PDF (1/18 Pages) IC-Haus GmbH – ANGULAR HALL SENSOR / ENCODER

iC-MA
ANGULAR HALL SENSOR / ENCODER
FEATURES
o Quadruple hall sensor array for error-tolerant adjustment
o Non-sensitive to magnetic stray fields due to differential
measurement technique
o Interpolator with a resolution of up to 256 angle steps per cycle
o Rotational speeds up to 60.000 rpm
o 4 buffered I/O stages for signal outputs
o Three configuration inputs for operating mode selection
o Analog operation modes:
- sine/cosine signals controlled to 2 Vpp
- triange or sawtooth signal with selectable amplitude
o Digital operation modes:
- A/B quadrature signals with Z index pulse
- Counter pulses for external binary counters
o Cascading of multiple iC-MA possible for chain operation
o Error signal output for detection of low magnetic field strength
o Additional operating modes with reduced power consumption
o Standby modus when not enabled
o DFN10 package and bare die for flip chip mounting available
o Extended temperature range of -40...+125 °C
