General Description

The SS275 Omnipolar Hall effect sensor IC is fabri-

cated from mixed signal CMOS technology .It incor-

porates advanced chopper-stabilization techniques to

provide accurate and stable magnetic switch points.

The output transistor of the SS275 will be latched on

(B_OP) in the presence of a sufficiently strong South or

North magnetic field facing the marked side of the

package. The output will be latched off (B_RP) in the

absence of a magnetic field.

The chopper stabilized amplifier uses switched capac-

itor techniques to eliminate the amplifier offset volt-

age, which, in bipolar devices, is a major source of

temperature sensitive drift. CMOS makes this ad-

vanced technique possible. The CMOS chip is also

much smaller than a bipolar chip, allowing very so-

phisticated circuitry to be placed in less space. The

small chip size also contributes to lower physical

stress and less power consumption.
