IC-MSA Datasheet, PDF (1/29 Pages) IC-Haus GmbH – SIN/COS SIGNAL CONDITIONER with AGC and 1Vpp DRIVER
iC-MSA SIN/COS SIGNAL
preliminary
CONDITIONER with AGC and 1Vpp DRIVER
FEATURES
o PGA inputs for differential and single-ended sensor signals up
to 20 kHz
o Selectable adaptation to voltage or current signals
o Flexible signal assignment due to input multiplexers
o Sine/Cosine signal conditioning for offset, amplitude and
phase
o Separate index signal conditioning
o Short-circuit-proof and reverse polarity tolerant output drivers
(1 Vpp to 100 Ω)
o Stabilized output signal levels due to automatic gain control
o Signal and system monitoring with configurable alarm output
o Supply voltage monitoring with integrated switches for
reversed-polarity-safe systems
o Excessive temperature protection with sensor calibration
o I2C multi-master interface
o Supply from 4.3 to 5 V, operation within -40 °C to +115 °C
o Verifyable chip release code
o Pin compatible with iC-MSB
Rev A1, Page 1/29
APPLICATIONS
o Programmable sensor interface
for optical and magnetic position
sensors
o Linear gauges and incremental
encoders
o Linear scales
