Voltage reference, REF102AU/2K5, Texas Instruments

The REF102AU/2K5 is a precision 10 V voltage reference. The drift is laser-trimmed to 2.5ppm/°C max C-grade over the industrial temperature range. This product achieves its precision without a heater, this results in low power, fast warm-up, excellent stability, and low noise. The output voltage is extremely insensitive to both line and load variations and can be externally adjusted with minimal effect on drift and stability. Single supply operation from 11.4 V to 36 V and excellent overall specifications make the REF102 an ideal choice for demanding instrumentation and system reference applications.
