AEAT-7000 Series

Ultra-precision 13-Bit Gray Code

Absolute Encoder Module

Data Sheet

Description

Avago Technologies’ AEAT-7000 Series is a high tempe-

rature rated optical encoder module that is capable of

providing up to 13 bits of absolute positioning infor-

mation. The photodetector ASIC and the light emitter

are designed into a compact C-shape module. It’s small,

compact and modular form factor also makes it an ideal

choice for space-constrained applications.

AEAT-7000 uses a sophisticated photodetector ASIC that

consists of an array of photodiodes, precision ampliﬁers,

and additional signal processing circuitry. This photode-

tector ASIC includes two pairs of analog photodiodes to

generate 2 channels of true diﬀerential Sine and Cosine

signals. For a closed loop emitter light monitoring, the

ASIC will monitor internally and self regulate if the infrared

(IR) LED degrades.

The Sin/Cosine photodiodes are used to drive a constant

current source for the highly collimated IR illumination

system.

Note: Avago Technologies encoders are not recommended

for use in safety critical applications, e.g., ABS braking

systems, power steering, life support systems and critical

care medical equipment. Avago’s products and software

are not speciﬁcally designed, manufactured or autho-

rized for sale as parts, components or assemblies for the

planning, construction, maintenance or direct operation

of a nuclear facility or for use in medical devices or ap-

plications. Customer is solely responsible, and waives all

rights to make claims against Avago or its suppliers, for all

loss, damage, expense or liability in connection with such

use. Please contact sales representative if more clariﬁca-

tion is needed.

ESD WARNING: Handling precautions should be taken to avoid static discharge.
