Overview
Agilent AEAS-7000 Plug and Play Ultra-Precision Absolute Encoder 16-bit Gray Code Data Sheet www.

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.
After conditioning they are on chip interpolated (4 bit) and computed to an absolute 6 bit Gray code.
Additionally, these Sin/Cos signals can be tapped as two true-differential analog outputs to be used at the system designer’s choice.
