可编程8位正余弦插补细分器, 带 EEPROM

Features      

• Interpolation rate fully programmable from 1 to 256 steps per cycle

• Latency less than 500 ns

• Direct sensor connection, selectable input gain, input signal 10 mV to 1.5 V peak-peak differential

• Max input frequency 460 kHz at interpolation rate <= 64, 230 kHz <= 115="" khz=""> 128

• Differential index gating input with fine adjustable offset (single ended by connection to VC)

• Output modes quadrature ABZ, up/down, increment/direction or 3 phase commutation

• Programmable filter and hysteresis

• Fully re-programmable with access to internal E2PROM to store setup and customer data

Applications

• Interpolator iC for position data acquisition from analog sin/cosine sensors

• Optical linear/rotary encoders

• Magneto resistive (MR) sensors/encoders
