REF102CU/2K5

Overview

The REF102CU/2K5 is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.1%. The device operates within an extended industrial temperature range of -40°C to +85°C and features a low temperature coefficient of 10ppm/°C. It requires an input voltage between 11.4V and 36V, draws a supply current of 1.4mA, and delivers up to 10mA of output current. Noise performance is specified at 5µVp-p from 0.1Hz to 10Hz. The component is housed in an 8-SOIC surface-mount package.
