Rev D2, Page 1/24
FEATURES
o Resolution of up to 8192 angle steps per sine/cosine period
o Binary and decimal resolution settings, e.g. 500, 512, 1000,
1024; programmable angle hysteresis
o Conversion time of just 250 ns including amplifier settling
o Count-safe vector follower principle, realtime system with
70 MHz sampling rate

o Front-end signal conditioning features offset (8 bit), amplitude
ratio (5 bit) and phase (6 bit) calibration
o 250 kHz input frequency
o Absolute angle output via fast SSI interface
o A QUAD B incremental outputs with selectable minimum
transition distance (e.g. 0.25 µs for 1 MHz at A)
o Index signal processing adjustable in position and width
o Fault monitoring: frequency, amplitude, configuration (CRC)
o Setup via serial EEPROM
o ESD protection and TTL-/CMOS-compatible outputs
APPLICATIONS
o Interpolator IC for position data
acquisition from analog
sine/cosine sensors
