differential Hall sensors, making it easier to

upgrade existing applications. Enhanced

sensitivity, ±7 Gauss typical allows for

larger air gaps (up to 2,5 mm [0.098 in])

and higher pole density (up to 50-pole

pairs depending on ring diameter).

Patented bridge array optimized to allow a

greater air gap between the target and the

APS00B.

Features: Dual bridges with outputs 45°

out of phase • Wide, angular range • Low

resolution capability • Absolute sensing

• Typical 0 MHz to 5 MHz frequency

response • Low power requirements

• Small 8-pin SOIC package on tape and reel.

Benets: Wide, angular range allows

measurements of ±90° without additional

components; measurements of ±180° are

possible with external components. Dual

Wheatstone bridges provide passive,

low-noise design, enhancing system

performance. Outputs 45° out of phase

may be used as speed and direction

signals. Resolution capability of less than

0.05° enhances overall system accuracy.

Absolute sensing means no indexing is

required and the exact target position

is known, simplifying system design.

Typical 0 MHz to 5 MHz frequency

response with 190 G minimum magnetic

ﬁeld applied makes this saturated mode

sensor suitable for potential high speed

applications. Measures only ﬁeld direction

and is virtually unaffected by shock,

vibration and magnetic-source gap

variations for stable and reliable output.
