The OHN3119U and OHS3119U each contain a monolithic integrated circuit which incorporates a Hall element, a . . linear amplifier, and Schmitt trigger ona Functional Block Diagram 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 Voc output and provides up to 21 mA of sink @ current. This allows direct driving of more than 7 TTL loads or any standard logic family using power supplies ranging from 4.5 to 24 volts. Output [re} amplitude is constant at switching 1 | output frequencies from DC to over 200 kHz. rl } i G) Package size has been kept to rT) minimum, providing an advantage in applications where space is limited.
