further from the zero-crossing. The output polarities are shown
in the Product Selection Guide table.
This variety of options provides flexibility for achieving solu-
tions for a wide range of applications, including automotive
transmission and crankshaft speed sensing.
The device package has an operating ambient temperature range
40癈 to 150癈 , and is provided in a 4-pin plastic SIP. Each
package is available in a lead (Pb) free version (suffix, T) , with
a 100% matte tin plated leadframe.
