Description (continued)
This device includes on a single silicon chip a Hall-voltage generator,
small-signal amplifier, chopper sta bi li za tion, a latch, and a MOSFET
output. Ad vanced BiCMOS processing is used to take advantage
of low-voltage and low-power requirements, component matching,
very low input-offset errors, and small component geometries.

NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The variants
should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available. Status
