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 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

2. 11 analog (A1-A11) channels which are directly

An internal correction and synchronization module

allows the composition of a true 16 bit Gray code by

merging the data bits of (1) and (2) by still keeping the

code monotonic.

There is a Gray code correction feature for this encoder.

This Gray code correction can be disabled/enabled by

the pin KORR.

The gain and offset conditioning value of the sine and

cosine signals are preloaded on-chip by factory. This

will compensate for mechanical sensor misalignment

error.

two 90° electrical shifted sine, cosine signals. These

signals are conditioned to be compensated for offset

and gain errors. After conditioning they are on chip

interpolated

digitized by precision comparators with hysterisis

tracking. The digitized signals are called D1-D11.

Features

• Minimum mechanical alignment during installation

• Two Sine/Cosine true differential outputs with 1024

• Integrated highly collimated illumination system

• 11 digital tracks plus 2 sin/cos tracks generate

• Ultra fast, 1 µs cycle for serial data output word

• On-chip interpolation and code correction

• MSB can be inverted for changing the counting

• Internally built-in monitor track for tracking the light

• Watch dog with alarm output

• –25°C to +85°C operating temperature

Applications

• Rotary application up to 16 bit/360° absolute

• Linear positioning system

• Cost effective solution for direct integration into

periods for unit alignment

... Gray code serial transfer rate is dependent on the SCL clock frequency. The faster the clock, the faster the transfer rate. The maximum clock rate the AEAS-7000 can take is 16 MHz, which means the entire 16 bit Gray code can be serially transferred out in 1 µs. ...
