特點(diǎn):
or negative gauss ? Quad Hall sensing element for stable output
? Power consumption of 7 mA at 5 VDC for energy efficiency
? Single current sinking or current sourcing output
Small size  (.160 x .118 in)
? Built-in thin film resistors are laser trimmed for precise sensitivity
and temperature compensation ? Rail-to-rail operation
provides more useable signal for higher accuracy
? Temperature range of -40°C to +150°C ? Responds to either positive
? Linear output for circuit design flexibility
