Functional Block Diagram
Description
The chip contains a monolithic integrated
circuit which incorporates a Hall element,
a linear amplifier, and Schmitt trigger on
a single silicon chip. Included on-chip is
a bandgap voltage regulator to allow
operation with a wide range of supply
voltages. The device features logic level
output and is capable of 25 mA of sink
current. Output amplitude is constant at
switching frequencies from DC to over
200 kHz.
The OMH360B is processed to Optek’
s
own screening procedures patterned
after class B of MIL-STD-883. OMH360S
is patterned after class S. Typical
screening and lot acceptance provided
on page 13-4.
