AM256Q –
For detailed sensor information, please refer to
the AM256 datasheet that can be found on
www.rls.si. The AM256Q has the same features,
specifications and performance in all respect to
the AM256 except that parallel digital outputs
are not provided.
Features
General description
The AM256Q uses the same technology as
the well known AM256 and AM256L
integrated circuits but is offered in the
compact QFN28 package (6x6 mm).
It offers Incremental and Serial (SSI) digital
outputs at 8 bit resolution as well as
Sinusoidal analogue outputs.
Contactless angular position encoding
over 360°
Ideal for harsh environments due to
magnetic sensing
Complete system-on-chip solution
8 bit absolute encoder
Output options:
Factory optimized linearity
High rotational speed up to 60,000 rpm
5 V power supply
Low power consumption: 13 mA typical
Extended operating temperature range
(-40 °C to +125 °C)
SMD package QFN28
RoHS compliant (lead free)
