AEAS-7500 Datasheet PDF - AVAGO Ultra-Precision 16 bit Gray Code Absolute Encoder Module Specs

AEAS-7500 - Ultra-Precision 16 bit Gray Code Absolute Encoder Module

Datasheet Summary

Description

The encoder IC consists of 13 signal photo diode channels and 1 monitor photo diode channel and is used for the optical reading of rotary or linear code carriers (i.e.

discs or www.DataSheet4U.com scales).

The photodiodes are accompanied with precision amplifiers plus additional circuitry.

Features

Two Sine/Cosine true differential outputs with 1024 periods for unit alignment.
Integrated highly collimated illumination system.
11 digital tracks plus 2 sin/cos tracks generate precise 16 bit Gray code.
Ultra fast, 1µs cycle for serial data output word equals 16MHz.
The 12 bits MSB is functionable up to 12000 RPM, 16 bit up to 1000RPM.
MSB can be inverted for changing the counting direction.
Monitor track for tracking the l.

AEAS - 7500 Ultra-Precision 16 bit Gray Code Absolute Encoder Module Data Sheet Description The encoder IC consists of 13 signal photo diode channels and 1 monitor photo diode channel and is used for the optical reading of rotary or linear code carriers (i.e. discs or www.DataSheet4U.com scales). The photodiodes are accompanied with precision amplifiers plus additional circuitry. The monitor channel is used to drive a constant current source for the highly collimated IR illumination system. Functional Description Background The 13 signal channels are set up as: 1. Two precision defining signals (A0, A09), which are two 90° electrical shifted sine, cosine signals. These signals are conditioned to be compensated for offset and gain errors.
