iC-MQ PROGRAMMABLE 9-BIT

Sin/Cos INTERPOLATION IC WITH RS422 DRIVER

Rev D4, Page 1/39

FEATURES

APPLICATIONS

♦ Optical and magnetic position

sensors

♦ Angle encoders

♦ Linear scales

♦ Latency-free sine-to-digital conversion to 400 angle steps

♦ 500 kHz input frequency for interpolation factors of x1 and x2

(10 kHz for x100)

♦ Flexible pin assignment due to signal path multiplexers

♦ PGA inputs for differential and single-ended signals

♦ Variable input resistance for current/voltage conversion

♦ Signal conditioning for offset, amplitude and phase

♦ Controlled 50 mA current source for LED or MR sensor supply

♦ Fault-tolerant RS422 outputs with 50 mA sink/source drive

current

♦ Preselectable minimum phase distance for spike-proof counter

stimulus

PACKAGES

♦ Zero signal conditioning and electronic index pulse generation

♦ Signal and operation monitoring with conﬁgurable alarm

output, output shutdown and error storage

♦ I²C multimaster interface for in-circuit calibration and

parameters (EEPROM)

♦ Adjustable overtemperature alarm and shutdown

♦ Supply from 4.3 to 5.5 V, operation from -25(-40) to +100 °C

♦ Reverse polarity proof including the sub-system

TSSOP20
