AEAS-7000 - Plug and Play Ultra-Precision Absolute Encoder 16-bit Gray Code

General 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 carriers (i.e., discs).

The photodiodes are accompanied with precision amplifiers plus additional circuitry.

Key Features

  • Minumum mechanical alignment during installation.
  • 2 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, 1 µs cycle for serial data output word equals 16 MHz.
  • On-chip interpolation and code correction to compensate for mounting tolerance.
  • MSB can be inverted for changing the.

Agilent AEAS-7000 Plug and Play Ultra-Precision Absolute Encoder 16-bit Gray Code Data Sheet www.DataSheet4U.com 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 carriers (i.e., discs). 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.
