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 OMH30198B is processed to Optek's own screening procedures patterned after class B of MIL-STD-883. OMH3019S is patterned after class S. Typical screening and lot acceptance tests are provided on page 13-4.
