Rev A2, Page 1/26
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, real-time system with a
70 MHz sampling rate
o Direct sensor connection; selectable input gain
o Front-end signal conditioning features offset (8 bits), amplitude
ratio (5 bits) and phase (6 bits) calibration
o Input frequency of up to 250 kHz
o Incremental A QUAD B outputs with a selectable minimum
transition distance (e.g. 0.25 µs for 1 MHz at A)
o Index signal processing adjustable in position and width
o Serial output of absolute angle data at clock rates of up to
10 MHz
o Error monitoring: frequency, amplitude, configuration (CRC)
o Multiturn counting up to 24 bits
o Device setup from serial EEPROM or 2-wire interface
o ESD protection and TTL-/CMOS-compatible outputs
APPLICATIONS
