The REF01 is a precision voltage reference manufactured by Analog Devices. It provides a stable 10V output that can be adjusted over a 3% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 12V to 40V, a low current drain of 1 mA, and excellent temperature stability are achieved with an improved band gap design. Low cost, low noise, and low power make the REF01 an excellent choice whenever a stable voltage reference is required.
The REFO1 precision voltage reference delivers a 10 V output that can be trimmed over a ±3 % range while maintaining excellent temperature stability (8.5 ppm/°C). It operates from a single supply of 12 V to 40 V and draws only about 1 mA of quiescent current, making it suitable for low‑power applications such as DACs, ADCs and portable instrumentation.
The datasheet includes electrical specifications, absolute maximum ratings, thermal resistance data, ESD precautions, typical performance curves, package dimensions and an ordering guide for the various REFO1 variants (TO‑99, CERDIP, PDIP, SOIC).
