REF3318AIDCKTG4 – TEXAS INSTRUMENTS

The Texas Instruments REF3318AIDCKTG4 is a low-noise, low-drift, precision voltage reference in a 4-pin SOT-23 package. It provides a highly stable 1.8V output with a typical initial accuracy of ±0.05% and a temperature coefficient of ±5ppm/°C over its operating temperature range of -40°C to +125°C. The device utilizes a bandgap architecture, minimizing long-term drift and ensuring stable operation across varying conditions. Its low output noise of 10µVrms (0.1Hz to 10Hz) makes it ideal for applications requiring high precision analog signal processing._x000D_
