Working Principle

The REF192GSZ-REEL voltage reference works as an ideal voltage source with a high degree of accuracy and stability. It is based on a voltage reference IC (integrated circuit) with a design that allows it to maintain a precise output voltage over a wide temperature range. The voltage reference IC is powered by an internal self-biased voltage source and draws a low quiescent current.

Once the device is powered up, the internal IC begins to regulate the output voltage. The reference voltage is calculated by the internal IC and a trim pin is used to adjust the volts/amp output. This ensured a precise output voltage that is stable and highly accurate.

To ensure a stable output voltage, the internal IC utilizes a temperature compensation circuit that adjusts the output voltage in order to counter the effects of temperature drift. This allows the REF192GSZ-REEL to provide a highly accurate, temperature stable, and precise output voltage with little need for adjustments.

Conclusion

The REF192GSZ-REEL voltage reference is a high precision voltage reference suitable for many applications. It offers enhanced stability and accuracy over a wide temperature range and is capable of reaching precision levels of 0.25%. It is available in a variety of packages such as the 8 lead SDIP, SOIC and the 14 lead TSSOP.

The REF192GSZ-REEL utilizes an internal self-biased voltage source, a trim pin, and a temperature compensation circuit to provide a precise output voltage. It is highly accurate and temperature-stable, making it ideal for precision applications in various industries such as automotive, telecommunications, healthcare and instrumentation.
