The REF02 is a precision voltage reference/temperature transducer produced by Analog Devices, Inc. It has a ±0.3% maximum output, a 1.96 mV/°C temperature voltage output, a ±3% minimum adjustment range, an 8.5 ppm/°C maximum temperature stability, a 15 µV p-p maximum noise, a 1.4 mA maximum supply current, a 7 V to 40 V wide input voltage range, a 10 mA high load-driving capability, no external components, and short-circuit protection.
The REF02 precision voltage reference from Analog Devices delivers a 5 V output that can be adjusted over a +6 % range while maintaining excellent temperature stability (8.5 ppm/°C). It operates from a single supply voltage of 7 V to 40 V and draws only 1.4 mA of supply current, making it suitable for portable instrumentation and digital voltmeters.
The device includes multiple package options (TO‑99, PDIP, CERDIP, SOIC, LCC) and features such as short‑circuit protection, low output noise (15 pV p‑p), and a high load‑driving capability of 10 mA. Detailed specifications, pin configurations, and ordering information are provided in the handbook.
