Chopper-Stabilized Omnipolar Hall-Effect Switch
Description (continued)
manufacturers to orient their magnets. These devices allow simple
on/off switching in industrial, consumer, and automotive applications.
The A1126 is rated for operation between the ambient temperatures
–40°C to 150°C. The available package styles provide magnetically
optimized solutions for most applications. Package LH is an SOT23W,
a miniature low-profile surface-mount package, while package
UA is a three-lead ultra-mini SIP for through-hole mounting. Each
package is lead (Pb) free, with 100% matte-tin-plated leadframe.
