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 OMHOSOB is processed to Opteks own screening procedures patterned after class B of MIL-STD-883. OMHOS0S is patterned after class S. Typical screeing and ict acceptance tests are provided on page 13-4.
