iC-TW2 8-BIT SIN/COS INTERPOLATION IC

WITH INTEGRATED EEPROM

Rev D3, Page 1/30

FEATURES

APPLICATIONS

♦ Programmable angle resolution from 1 to 256 steps per period

♦ Interpolation factors from x0.25 to x64

♦ Input frequency to 115 kHz with x64, to 230 kHz with x32, to

460 kHz with x16

♦ Interpolation IC for position data

acquisition from analog

sine/cosine sensors

♦ Optical linear and rotary

encoders

♦ Latency of less than 1 µs

♦ Magneto resistive sensors and

encoders

♦ Selectable gain permits single-ended and differential input

signals from 10 mV to 1.5 V peak-peak

♦ Index gating input with ﬁne adjustable offset

♦ Programmable index pulse output position and width

♦ Four incremental output modes: quadrature encoder with

index, up/down clock, increment/direction, 3 phase

commutation

PACKAGES

♦ Programmable ﬁlter and hysteresis

♦ Direct sensor connection, minimized count of external

components

♦ Non-volatile setup due to internal EEPROM

♦ Fully re-programmable via serial 1- and 2-wire interfaces

♦ Power-on reset circuit and on-chip oscillator

♦ ESD protection and TTL-/CMOS-compatible outputs
