Texas Instruments REF80 Temp-Controlled Buried Zener Reference

Texas Instruments REF80 Temperature-Controlled Buried Zener Reference combines a precision 7.6V reference with an internal heater to achieve a low-temperature drift of 0.05ppm/°C. The integrated heater keeps the internal temperature of the die at a constant set point, which helps the reference voltage stay constant regardless of ambient temperature variations. The internal temperature is pre-programmed to eliminate design complexities, enabling fast design cycles, easy bring-up, and no dependence on costly external precision components. This highly integrated reference features a 20-pin LCCC hermetically sealed ceramic package that provides excellent long-term stability of <1ppm. Texas Instruments REF80 Temperature-Controlled Buried Zener Reference is ideal for parametric and source measurement units, lab and field instrumentation, weight scales, battery-test equipment, digital multimeters, and data acquisition applications.
