13-bit Sin/D CONVERTER WITH SSI INTERFACE

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 Direct sensor connection; selectable input gain

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

o Optical linear/rotary encoders

o MR sensor systems
