Description:

The iC-PZ is a complete lensless optical reflective absolute encoder IC.

With its integrated blue LED and interpolator, the iC-PZ provides

a high-resolution single-chip absolute linear or rotary encoder

solution. Independently configurable BiSS/SSI, ABZ, UVW, SPI, and

analog Sin/Cos outputs may be used singly or in combination to

provide a highly flexible system. FlexCount ® and FlexCode ® allow

arbitrary ABZ resolution and arbitrary code disc diameter.

Automatic calibration corrects for sin/cos signal errors (offset, gain,

and phase) and code wheel eccentricity without requiring external

hardware or software. Calibrated parameter values are stored in an

external EEPROM. Wide assembly tolerances ensure that the iC-PZ

is easy to install and align, making design-in to any application

simple.
