KMZ43T.rar - DESCRIPTION
The KMZ43T is a sensitive magnetic field sensor,
employing the magnetoresistive effect of thin-film
permalloy. The sensor contains two galvanic separated
Wheatstone bridges, at a relative angle of 45° to one
another.
A rotating magnetic field in the x-y plane will produce two
independent sinusoidal output signals, one a function of
+cos(2a) and the second a function of +sin(2a), a being
the angle between sensor and field direction (see Fig.3).
Unlike the KMZ41(1), which needs a saturation field
strength of 100 kA/m, the KMZ43T is suited to high
precision angle measurement applications under low field
conditions (saturation field strength 25 kA/m).
The sensor can be operated at any frequency between
DC and 1 MHz.
The information in application notes AN00023
(Contactless Angle Measurement Using KMZ41 and
UZZ9000) and AN00004 (Contactless Angle
Measurement Using KMZ41 and UZZ9001) is applicable
to the KMZ43T, but one should be aware of the difference,2013-03-23 10:12:20,下载1次
UZZ9001.rar - FEATURES
· One chip angle sensor output signal conditioning
· 180° angle range with KMZ41
· Accuracy better than 1° together with KMZ41
· Temperature range from -40 to +150 °C
· SPI protocol
· SO24 package.
GENERAL DESCRIPTION
The UZZ9001 is an integrated circuit that combines two
sinusoidal signals (sine and cosine) into one single linear
output signal. These signals might come from the
magnetoresistive sensor KMZ41. This results in a
measurement system for angles up to 180°. The
integrated circuit UZZ9001 can also be used for all other,2013-03-23 10:10:47,下载1次
522JI.rar - CAT522JI
The CAT522 is a dual, 8-bit digitally-programmable
potentiometer (DPP™ ) configured for programmable
voltage and DAC-like applications. Intended for final
calibration of products such as camcorders, fax
machines and cellular telephones on automated high
volume production lines, it is also well suited for
self-calibrating systems and for applications where
equipment which requires periodic adjustment is either
difficult to access or in a hazardous environment,2013-03-22 21:07:26,下载1次
